VASCULAR NEUROCOGNITIVE DISORDER


WARNING:



President Trump is about to start a nuclear war with North Korea. New UN sanctions have cut North Korea's oil and money supply - hence its regime would soon fall without war. Both China and Russia have promised to defend North Korea if America attacks first. So America attacking North Korea could start a nuclear WW III. Nevertheless, Trump will attack North Korea as a distraction from his possible impeachment. US pro-war propaganda is becoming hysterical. This propaganda lies in stating that "food supplies would be decimated by radiation and up to 90% of the population would die within a year" after a nuclear bomb was exploded high in the atmosphere over America. The truth is that an electromagnetic pulse from such a high atmospheric nuclear explosion could destroy electronic devices for hundreds of miles beneath the blast. But the resulting electromagnetc pulse from such a blast is not lethal to humans. In the 1950s and 1960s, thousands of American soldiers were experimentally placed in trenches just a few miles from ground nuclear explosions, and the resulting electromagnetic pulse did not kill one of these American soldier "guinea pigs". However, this high radiation exposure decades later caused a dramatic increase in cancer in these human guinea pigs. The high radiation exposure from the Chernobyl Disaster did not kill the surrounding vegetation or animals.

Why Is This Warning On A Mental Health Website?

No such warning has ever been published on this website since its creation in 1995. However, the very high probability of a nuclear WW III, and the certainty of irreversible climate change in the next few years requires that this warning be posted. If Trump starts WW III, or does nothing to stop climate change, mental illness will be the least of our worries.

VASCULAR NEUROCOGNITIVE DISORDER

  • Gradual/acute onset and fluctuating/gradual progressive decline in one or more cognitive domains (complex attention, executive function, learning and memory, language, perceptual-motor, or social cognition):

    • Course: Usually there is a stepwise decline or fluctuating course, with intervening periods of stability and even some improvement. Less often there is a steadily progressive, gradual decline in cognitive functioning (similar to that of Neurocognitive Disorder Due To Alzheimer's Disease).

    • Gradual onset: occurs following a number of transient ischaemic episodes which produce an accumulation of brain infarcts.

    • Acute onset: develops rapidly after a succession of strokes from cerebrovascular thrombosis, embolism or haemorrhage. In rare cases, a single large infarction may be the cause.

    • When mild: One or more cognitive domains may be impaired, but this does not interfere with independence in everyday activities (e.g., paying bills or managing medications).

    • When major: At least two cognitive domains are impaired, and this interferes with independence in everyday activities.

  • The cognitive deficits are consistent with a vascular etiology, as suggested by either:

    • Onset of the cognitive deficits is temporally related to one or more cerebrovascular events.

    • Evidence for decline is prominent in complex attention (including processing speed) and executive functioning.

      • Complex attention and executive functioning primarily represent functioning of the frontal lobes of the brain.

  • There is evidence of the presence of cerebrovascular disease from history, physical examination, and/or neuroimaging considered sufficient to account for the neurocognitive deficits.

  • The cognitive deficits are not better explained by another brain disease or systemic disorder.

Prediction

    Chronic and progressive: The disease progresses in a fluctuating, stepwise manner, sometimes with brief plateaus, until severe dementia and death. Can occur at any age, although the prevalence increases exponentially after age 65. The average survival time from diagnosis is around 4 years. Most people will die either from complications of dementia, such as pneumonia, or from a subsequent stroke.

Problems

    Occupational-Economic Problems:

    • Impairment in social and occupational functioning ranges from none (at the start) to severe (at the end).

    • Reaches the point where can't do usual daily activities (e.g., driving, money management, grocery shopping).

    • Eventually needs total nursing care.

    Critical, Quarrelsome (Antagonism):

    • May become violent.

    Impulsive, Disorderly (Disinhibition):

    • May become impulsive, reckless, disrespectful and/or irresponsible.

    Cognitive Decline (Impaired Intellect):

    • Has significant cognitive decline in one (or more) of:

      • Complex attention: e.g., is unable to pay attention unless input is restricted and simplified; all thinking takes longer than usual; has difficulty holding new information in mind, such as reporting what was just said.

      • Executive function: loss of the ability to plan, make decisions, hold information briefly in memory to manipulate it (e.g., mental arithmetic), respond to feedback/error correction, override/inhibit old habits to learn new behaviors, or to have mental flexibility (ability to shift between two concepts, tasks, or response rules).

        • Prominent decline in complex attention and executive function is highly suggestive of vascular neurocognitive disorder.

      • Learning and memory: repeats self in conversation, can't keep track of a short list of items when shopping or of plans for the day; requires frequent reminders to orient to the task at hand; can't repeat a list of words or digits.

        • Recent memory (memory for recent events) is impaired long before remote memory (memory acquired long ago).

        • Thus the last memories to be lost are: semantic memory (memory for facts), autobiographical memory (memory for personal events or people), and implicit (procedural) learning (unconscious learning of skills - like how to ride a bicycle).

      • Language: loss of the ability to speak or understand spoken or written language (aphasia).

      • Perceptual-motor: impaired ability to integrate perception with purposeful movement despite intact motor function; e.g., has significant difficulties with previously familiar activities (using tools, driving), or navigating in familiar environments; is often more confused at dusk, when shadows and lowering levels of light change perceptions.

        • Agnosia (failure to recognize or identify objects despite intact sensory function).

        • Apraxia (impaired ability to carry out motor activities despite intact motor function).

      • Social cognition: loss of the ability to recognize other's emotions or what they are thinking:

        • Mild: e.g., has a change in personality, such as less abillity to recognize social cues or read facial expressions, decreased empathy, increased extraversion or introversion, decreased inhibition, or subtle or episodic apathy or restlessness.

        • Major: e.g., behavior clearly out of acceptable social range; shows insensitivity to social standards of modesty in dress or of political, religious, or sexual topics of conversation; inappropriate clothing for weather or social setting.

    • When severe, may have delusions, hallucinations, and/or confusion.

    Anormally Inhibited or Disinhibited (Low or High Extraversion):

    • Social withdrawal (due to confusion).

    • May be hyperactive, hypoactive, or a mixture of both.

    Distressed, Easily Upset (Negative Emotion):

    • Mood may be anxious, depressed or highly changable.

    • "Vascular depression": the development of late-onset depression accompanied by psychomotor slowing and impaired executive functioning is a common presentation among older adults with progressive small vessel ischemic disease.

    Medical:

    • Must have evidence of cerebrovascular disease of sufficient severity to account for the neurocognitive deficits, either:

      • Clinical criteria are supported by neuroimaging evidence of significant parenchymal injury attributed to cerebrovascular disease (neuroimaging-supported).

      • The neurocognitive syndrome is temporally related to one or more documented cerebrovascular events.

      • Both clinical and genetic (e.g., cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) evidence of cerebrovascular disease is present.

    • Unlike most other dementias, has focal neurological signs (e.g., exggeration of deep tendon reflexes, extensor plantar response, psuedobulbar palsy, gait abnormalities, weakness of an extremity).

    • Neuroimaging shows multiple vascular lesions of the cerebral cortex and subcortical structures; evidence of old infarctions (e.g., focal atrophy) may be detected, as well as findings of more recent disease.

    • EEG findings may reflect focal lesions in the brain.

    • Laboratory evidence of associated cardiac and systemic vascular conditions (e.g., ECG abnormalities, laboratory evidence of renal failure).

    • Often evidence of long-standing arterial hypertension (e.g., funduscopic abnormalities, enlarged heart), vavular heart disease (e.g., abnormal heart sounds), or or extracranial vascular disease that may be sources of cerebral emboli.

    • A single stroke may cause a relatively circumscribed change in mental state (e.g., just aphasia or an amnestic disorder), but generally does not cause Vascular Neurocognitive Disorder, which typically results from the occurrence of multiple strokes.

    • Usually has denial of illness.

Vascular Dementia F01 - ICD10 Description, World Health Organization
Vascular dementia is the result of infarction of the brain due to vascular disease, including hypertensive cerebrovascular disease. The infarcts are usually small but cumulative in their effect. Onset is usually in later life.

    F01.0 Vascular dementia of acute onset

    Usually develops rapidly after a succession of strokes from cerebrovascular thrombosis, embolism or haemorrhage. In rare cases, a single large infarction may be the cause.

    F01.1 Multi-infarct dementia

    Gradual in onset, following a number of transient ischaemic episodes which produce an accumulation of infarcts in the cerebral parenchyma. Predominantly cortical dementia.

    F01.2 Subcortical vascular dementia

    Includes cases with a history of hypertension and foci of ischaemic destruction in the deep white matter of the cerebral hemispheres. The cerebral cortex is usually preserved and this contrasts with the clinical picture which may closely resemble that of dementia in Alzheimer disease.

    F01.3 Mixed cortical and subcortical vascular dementia

Vascular Neurocognitive Disorder - Diagnostic Criteria, American Psychiatric Association

An individual diagnosed with vascular neurocognitive disorder needs to meet all of the following criteria:

  • The criteria are met for major or mild neurocognitive disorder:

    • Major Neurocognitive Disorder

    • Evidence of significant cognitive decline from a previous level of performance in one or more cognitive domains (complex attention, executive function, learning and memory, language, perceptual-motor, or social cognition) based on:

      • Concern of the individual, a knowledgeable informant, or the clinician that there has been a significant decline in cognitive function; and

      • A substantial impairment in cognitive performance, preferably documented by standardized neuropsychological testing or, in its absence, another quantified clinical assessment.

    • The cognitive deficits interfere with independence in everyday activities (i.e., at a minimum, requiring assistance with complex instrumental activities of daily living such as paying bills or managing medications).

    • The cognitive deficits do not occur exclusively in the context of a delirium.

    • The cognitive deficits are not better explained by another mental disorder (e.g., major depressive disorder, schizophrenia).

    • Mild Neurocognitive Disorder

    • Evidence of modest cognitive decline from a previous level of performance in one or more cognitive domains (complex attention, executive function, learning and memory, language, perceptual-motor, or social cognition) based on:

      • Concern of the individual, a knowledgeable informant, or the clinician that there has been a mild decline in cognitive function; and

      • A modest impairment in cognitive performance, preferably documented by standardized neuropsychological testing or, in its absence, another quantified clinical assessment.

    • The cognitive deficits do not interfere with capacity for independence in everyday activities (i.e., complex instrumental activities of daily living such as paying bills or managing medications are preserved, but greater effort, compensatory strategies, or accommodation may be required).

    • The cognitive deficits do not occur exclusively in the context of a delirium.

    • The cognitive deficits are not better explained by another mental disorder (e.g., major depressive disorder, schizophrenia).

  • The clinical features are consistent with a vascular etiology, as suggested by either of the following:

    • Onset of the cognitive deficits is temporally related to one or more cerebrovascular events.

    • Evidence for decline is prominent in complex attention (including processing speed) and fronto-executive function.

  • There is evidence of the presence of cerebrovascular disease from history, physical examination, and/or neuroimaging considered sufficient to account for the neurocognitive deficits.

  • The symptoms are not better explained by another brain disease or systemic disorder.

  • Probable vascular neurocognitive disorder is diagnosed if one of the following is present; otherwise possible vascular neurocognitive disorder should be diagnosed:

    • Clinical criteria are supported by neuroimaging evidence of significant parenchymal injury attributed to cerebrovascular disease (neuroimaging-supported).

    • The neurocognitive syndrome is temporally related to one or more documented cerebrovascular events.

    • Both clinical and genetic (e.g., cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) evidence of cerebrovascular disease is present.

  • Possible vascular neurocognitive disorder is diagnosed if the clinical criteria are met but neuroimaging is not available and the temporal relationship of the neurocognitive syndrome with one or more cerebrovascular events is not established.

Diagnostic Features

Vascular Neurocognitive Disorder shows cognitive decline from a previous level of performance in one or more cognitive domains of higher cortical functioning:

  • Complex attention: e.g., is unable to pay attention unless input is restricted and simplified; all thinking takes longer than usual; has difficulty holding new information in mind, such as reporting what was just said.

  • Executive function: loss of the ability to plan, make decisions, hold information briefly in memory to manipulate it (e.g., mental arithmetic), respond to feedback/error correction, override/inhibit old habits to learn new behaviors, or to have mental flexibility (ability to shift between two concepts, tasks, or response rules).

  • Learning and memory: repeats self in conversation, can't keep track of a short list of items when shopping or of plans for the day; requires frequent reminders to orient to the task at hand; can't repeat a list of words or digits.

  • Language: loss of the ability to speak or understand spoken or written language (aphasia).

  • Perceptual-motor: impaired ability to integrate perception with purposeful movement despite intact motor function; e.g., has significant difficulties with previously familiar activities (using tools, driving), or navigating in familiar environments; is often more confused at dusk, when shadows and lowering levels of light change perceptions.

  • Social cognition: loss of the ability to recognize other's emotions or what they are thinking:

These cognitive deficits are consistent with a vascular etiology, and eventually cause significant impairment in social or occupational functioning.

Cerebrovascular Disease

Unlike most other dementias, this disorder has focal neurological signs and symptoms (e.g., exggeration of deep tendon reflexes, extensor plantar response, psuedobulbar palsy, gait abnormalities, weakness of an extremity) or laboratory evidence indicative of cerebrovascular disease (e.g., multiple infarctions involving cortex and underlying white matter) that are judged to be etiologically related to the disturbance. The deficits do not occur exclusively during the course of a delirium.

Effective Therapies

For mild to moderate Vascular Neurocognitive Disorder, the cholinesterase inhibitor, donepezil, been shown to improve cognition functioning and activities of daily living for a number of months, but then the benefit is lost. With elderly demented individuals, atypical antipsychotic medications significantly increase mortality; thus they should only be used to treat aggressive or psychotic demented patients when there is severe distress or risk of physical harm to those living and working with the patient. Psychosocial interventions (supervised day activity programs, nursing home/extended care placement, disability pensions or government financial aid) and caregiver support are key to managing this disorder. Caregiver support groups are very beneficial to caregivers.

Which Behavioral Dimensions Are Involved?

Research has shown that there are 5 major dimensions (the "Big 5 Factors") of personality disorders and other mental disorders. There are two free online personality tests that assess your personality in terms of the "Big 5 dimensions of personality.

This website uses these 5 major dimensions of human behavior to describe all mental disorders. (This website adds one more dimension, "Physical Health", but our discussion will focus on the first 5 major dimensions.)

These 5 major dimensions of human behavior seem to represent 5 major dimensions whereby our early ancestors chose their hunting companions or spouse. To maximize their chance for survival, our ancestors wanted companions who were agreeable, conscientious, intelligent, enthusiastic, and calm.

    Which Dimensions of Human Behavior are Impaired in Vascular Neurocognitive Disorder?

    THE POSITIVE SIDE OF THE "BIG 5" PERSONALITY DIMENSIONS THE NEGATIVE SIDE OF THE "BIG 5" PERSONALITY DIMENSIONS DESCRIPTION (Where red = this disorder)
    Agreeableness Antagonism       Sympathetic, Kind vs. Critical, Quarrelsome
    Conscientiousness Disinhibition       Industrious, Orderly vs. Impulsive, Disorderly
    Openness To Experience Impaired Intellect       Open-Minded, Creative vs. Cognitive Impairment

The 5 Major Dimensions of Mental Illness

Our website uses the "Big 5 Factors" of personality as major dimensions of mental illness. Each of these 5 dimensions has a healthy side and an unhealthy side. The Big 5 Factors are: Agreeableness, Conscientiousness, Openness to Experience, Sociability (Extraversion), and Emotional Stability. Our website adds an additional factor, Physical Health. However, our discussion will primarily focus on the traditional "Big 5 Factors".

Agreeableness (Sympathetic, Kind)
.
Description: Agreeableness is synonymous with compassion and politeness; whereas Antagonism is synonymous with competition and aggression. Compassion reflects empathy, sympathy, and caring for others. Politeness reflects respect for others’ needs and desires and a tendency to refrain from aggression.

OPENNESS TO EXPERIENCE vs. IMPAIRED INTELLECT
.
Open To Experience (Open-Minded, Creative)
.
Description: Open to Experience is synonymous with being open-minded and creative; whereas Closed to Experience is synonymous with being closed-minded and uncreative. The Openness to Experience dimension measures the behaviors that are central to the concept of WISDOM.

They are creative, flexible, and holistic in their thinking. They never stop questioning.
Descriptors: Wide interests, imaginative, intelligent, original, insightful, curious, sophisticated, artistic, clever, inventive, sharp-witted, wise
MRI Research*: Openness To Experience did not have any significant correlation with the volume of any brain structures. (This could suggest that "Openness To Experience", as defined here, is more a function of culture rather than of brain neurobiology.)

"It's weird, but sometimes ordinary objects seem to be a different shape than usual."
"Sometimes I feel 'controlled' by thoughts that belong to someone else."
"Sometimes I think someone else is removing thoughts from my head."
"I have periods in which I feel disconnected from the world or from myself."
"I can have trouble telling the difference between dreams and waking life."
"I often 'zone out' and then suddenly come to and realize that a lot of time has passed."
"Sometimes when I look at a familiar object, it's somehow like I'm seeing it for the first time."
"People often talk about me doing things I don't remember at all."
"I often can't control what I think about."
"I often see vivid dream-like images when I’m falling asleep or waking up."

EMOTIONAL STABILITY VS. NEGATIVE EMOTION
.
Emotional Stability (Calm, Emotionally Stable)
.
Description: Emotional Stability is synonymous with being calm and emotionally stable; whereas Negative Emotion is synonymous with being distressed and easily upset. The Emotional Stability dimension measures the "safety vs. danger" behaviors that are central to the concept of COURAGE.
Descriptors: Stable, calm, relaxed, contented
"I am relaxed, and I handle stress well."
"I am emotionally stable, and not easily upset."
"I remain calm in tense situations."
"I rarely get irritated."
"I keep my emotions under control."
"I rarely lose my composure."
"I am not easily annoyed."
"I seldom feel blue."
"I feel comfortable with myself."
"I rarely feel depressed."
"I am not embarrassed easily."
.
Negative Emotion (Distressed, Easily Upset)
.
Description: Degree to which people experience persistent negative emotions (anxiety, anger, or depression) and are easily upset. (This could be thought of as high threat sensitivity or low stress tolerance.)
Descriptors: Emotional instability, anxiety, irritability, depression, rumination-compulsiveness, self-consciousness, vulnerability
MRI Research*: Negative Emotion was associated with increased volume of brain regions associated with threat, punishment, and negative emotions.

  • The best summary on bad research is given by Laura Arnold in this Tedx lecture. If you read nothing else about research, you owe it to yourself to watch this short video - it is excellent!

  • Criteria For High Quality Research Studies

  • It is imperative that medical researchers conduct high quality research studies, otherwise the US Food and Drug Administration (FDA) refuses to licence their new drug or therapy. In 2009, the cost of successfully licensing one new drug or therapy under the FDA scheme was estimated to be US$1,000 million. Thus psychiatric research which leads to FDA approval of a new drug or therapy has to be of the highest quality; however the majority of psychological research studies on new therapies fail to reach these high standards for research. This could explain why two-thirds of psychological research studies can't be replicated. High quality research must meet the following criteria:

    • Randomized Controlled Trial:
      Ask: Was the trial randomized? Was the randomization procedure described and was it appropriate? The best research design is to have research subjects randomly assigned to an experimental or control group. It is essential that confounding factors be controlled for by having a control group or comparator condition (no intervention, placebo, care as usual etc.).

    • Representative Sample:
      Ask: Do the research subjects represent a normal cross-section of the population being studied? Many psychological research studies using university students are flawed because their subjects are not representative of the normal population since they are all W.E.I.R.D. (White, Educated, Intelligent, Rich, and living in a Democracy).

    • Single Blind Trial:
      Ask: Was the treatment allocation concealed? It is essential that the research subjects are kept "blind" as to whether they are in the experimental or control group (in order to control for any placebo effects).

    • Double Blind Trial (Better Than Single Blind Trial):
      Ask: Were blind outcome assessments conducted? In a double blind study, neither the research subjects nor the outcome assessors know if the research subject is in the experimental or control group. This controls for both the placebo effect and assessor bias.

    • Baseline Comparability:
      Ask: Were groups similar at baseline on prognostic indicators? The experimental and control groups must be shown to be comparable at the beginning of the study.

    • Confounding Factors:
      Ask: Were there factors, that weren't controlled for, that could have seriously distorted the study's results? For example, research studies on the effectiveness of mindfulness cognitive therapy in preventing depressive relapse forgot to control for whether the research subjects were also simultaneously receiving antidepressant medication or other psychological treatments for depression.

    • Intervention Integrity:
      Ask: Was the research study protocal strictly followed? The research subjects must be shown to be compliant (e.g., taking their pills, attending therapy) and the therapists must be shown to be reliably delivering the intervention (e.g., staying on the research protocol).

    • Statistical analysis:
      Ask: Was a statistical power calculation described? The study should discuss its statistical power analysis; that is whether the study size is large enough to statistically detect a difference between the experimental and control group (should it occur) and usually this requires at least 50 research subjects in the study.

      Ask: Are the results both statistically significant and clinically significant? The results should be both statistically significant (with a p-value <0.05) and clinically significant using some measure of Effect Size such as Standardized Mean Difference (e.g., Cohen's d >= 0.33). The summary statistics should report what percentage of the total variance of the dependent variable (e.g., outcome) can be explained by the independent variable (e.g., intervention). In clinical studies, the study should report the number needed to treat for an additional beneficial outcome (NNTB), and the number needed to treat for an additional harmful outcome (NNTH).

        Number Needed To Benefit (NNTB): This is defined as the number of patients that need to be treated for one of them to benefit compared with a control in a clinical trial. (It is defined as the inverse of the absolute risk reduction.) Note: Statistically, the NNTB depends on which control group is used for comparison - e.g., active treatment vs. placebo treatment, or active treatment vs. no treatment.

        Number Needed To Harm (NNTH): This is defined as the number of patients that need to be treated for one of them to be harmed compared with a control in a clinical trial. (It is defined as the inverse of the absolute increase in risk of harm.)

        Tomlinson found “an NNTB of 5 or less was probably associated with a meaningful health benefit,” while “an NNTB of 15 or more was quite certain to be associated with at most a small net health benefit.”

      Ask: Does the researcher accept full responsibility for the study's statistical analysis? The researcher should not just hand over the study's raw data to a corporation (that may have $1,000 million invested in the study) to do the statistical analysis.

    • Completeness of follow-up data:
      Ask: Was the number of withdrawals or dropouts in each group mentioned, and were reasons given for these withdrawals or dropouts? Less than 20% of the research subjects should drop out of the study. The intervention effect should persist over an adequate length of time.

    • Handling of missing data:
      Ask: Was the statistical analysis conducted on the intention-to-treat sample? There must be use of intention-to-treat analysis (as opposed to a completers-only analysis). In this way, all of the research subjects that started the study are included in the final statistical analysis. A completers-only analysis would disregard those research subjects that dropped out.

    • Replication of Findings:
      Ask: Can other researchers replicate this study's results? The research study's methodology should be clearly described so that the study can be easily replicated. The researcher's raw data should be available to other researchers to review (in order to detect errors or fraud).

    • No Suspicion Of Fraud: There is a high suspicion of fraud in a study's summary statistics (for independent or dependent variables that can only take non-negative values):
      • If the SD is mathematically impossible (online calculator): (i.e.,
      • No Suspicion Of Fraud: There is a high suspicion of fraud in a study's summary statistics (for independent or dependent variables that can only take non-negative values):
        • If the SD is mathematically impossible (online calculator): (i.e., if the data range for the non-zero variable extends below zero [which should be impossible]; for a sample size 25-70, this occurs when the SD is greater than one-half of the M; for a sample size of 70+, this occurs when the SD is greater than one-third of the M [using these formulas])

        • If the SD/M is very small (i.e., the variable's standard deviation is very small compared to the mean suggesting data smoothing)

        • If the SD's are almost identical (i.e., the variables have different means but almost identical standard deviations)

        • If the 4th digit of the values of the variables aren't uniformly distributed - since each should occur 10% of the time (Benford's Law)

        )

      • If the SD/M is very small (i.e., the variable's standard deviation is very small compared to the mean suggesting data smoothing)

      • If the SD's are almost identical (i.e., the variables have different means but almost identical standard deviations)

      • If the 4th digit of the values of the variables aren't uniformly distributed - since each should occur 10% of the time (Benford's Law)

      • If the research study's data contradicts the study's own conclusions - surprisingly, this often occurs.

  • Calling Bullshit In The Age of Big Data - "Bullshit is language, statistical figures, data graphics, and other forms of presentation intended to persuade by impressing and overwhelming a reader or listener, with a blatant disregard for truth and logical coherence." Reading the syllabus of this university course should be required reading for every student of mental health. This syllabus is absolutely fantastic!
