Although I don't know any publications exactly on that matter it is possible to be true. So please treat this as a speculation. People with Asperger Syndrome (or High-Functioning Autism) have higher attention to detail and tend to build more rigid structures in their minds (while neurotypicals may have more error-tolerant but less efficient structures). So ...

ADHD is not 'caused' by a brain structure. However, there are observable differences in the brains of ADHD sufferers compared to non-ADHD sufferers. For example, ADHD sufferers have a disproportionately greater decrease in volume in the left side of the prefrontal cortex, as well as the posterior parietal cortex. In addition, there is typically a reduction ...

General thoughts on factors influencing test-retest correlations From a theoretical perspective, it makes sense that groups that experience temporary states that lower state intelligence or lead to a poorer test taking orientation would have lower test-retest cognitive test correlations. By lower state intelligence, I'm referring to states of being such as ...

Short answer: Bipolar disorder is probably not composed of two comorbid illnesses, but it may be on a continuum that includes some depressive disorders. This is a good question, though it does convey some confusion associated with this diagnosis that should be cleared up. Bipolar symptoms: The first confusion I think is the idea that "depression", ...

Sounds to me like someone is making a logical fallacy here, though the origin of this fallacy isn't clear to me. We cannot go from 'poor academic performance', to 'not amounting to anything', to 'having a low IQ'. These are not relationships of cause and effect. The motivation to do something ('amount to something', if you will) is driven primarily by the ...

Like all psychiatric disorers, ADD and ADHD are diagnosed using a set of criteria listed in the Diagnostic and Statistical Manual of Mental Disorders, or DSM The latest version is the DSM-IV-TR. The DSM-V is due out in 2013 and may change these criteria. Diagnosis is expected to be done by a licensed professional who is able to assess these criteria. From ...

Yes, they can coexist. No, they aren't opposites. How could they be? Both ADHD and OCD affect a variety of different brain regions, and its effects are not consistent in every person. Maybe if OCD and all its symptoms were always caused by an excess of dopamine in one specific pathway in the reward system, whereas ADHD and all its symptoms was always caused ...

They are interchangeable. ADD was a term used until around the mid 80s and ADHD aftewards. In the Diagnostic and Statistical Manual of Mental Disorders 1980 (DSM-III) published by the American Psychiatric Association (APA) it was named ADD and the name changed to ADHD in the 1987 edition, DSM-III-R (which I can find no online sources of). ADD has been ...

ADHD is considered a neurodevelopmental disorder. Neurodevelopmental disorders are impairments of the growth and development of the brain or central nervous system. A narrower use of the term refers to a disorder of brain function that affects emotion, learning ability, self-control and memory and that unfolds as the individual grows. You are correct ...

I myself have never found evidence to suggest a difference between perseveration and hyperfocus when referring to ADHD. However, while 'hyperfocus' can be a psychiatric or non-psychiatric condition, perseveration is typically considered a psychiatric condition in all instances. The wikipedia page for hyperfocus has an entire section dedicated to the ...

How do the rationality and logical thought processes those with and without ADHD compare? Please explain the source of this difference. Is the difference thought to be caused by dopamine, serotonin or norepinephrine or some other neurological explanation. ADHD is typically associated with a reduction in dopamine and/or norepinephrine. Though the two ...

Your question is very broad. But from my reading of the literature, my hypothesis would be that there wouldn't be a difference in the degree to which learning curves are logistic. In a very general sense, learning generally involves the accumulation of a vast number of smaller components. Some components are easier to acquire than others and some yield ...

Whether or not there is truth to this theory, a ketogenic diet cannot 'eliminate ADHD symptoms'. ADHD is an impairment of executive functioning. Executive dysfunction is thought to be linked to a deficit in dopamine, as well as functional frontal lobe pathology. (1) There are certainly other theories as to what causes the disorder, and they are likely a ...

There actually is the same kind of controversy over depression. The French documentary Dépression, une épidémie mondiale nicely summarizes how a well-meant change in diagnostic criteria (from DSM-IV to DSM-5) backfired and the pharmacoceutical industry now use this to diagnose every sadness or exhaustion as depression with the intention to sell drugs and ...

I hope the few sources below answer your question. I strongly recommend you read actual sources as opposed to the parts I have quoted. I don't know much about this topic so I did not attempt to translate anything in laymen terms, since I might have distorted or misinterpreted information in the process. However, the three sources below are one of the ...

Short answer Don't believe everything you read. Background The article cited (Kirsch, 2014) appears in a German journal with a mediocre impact factor. Not the most convincing platform. I'll cite parts of the abstract, starting with But analyses of the published data and the unpublished data that were hidden by drug companies reveals that most ...

Upon closer examination, it appears that Rejection Sensitive Dysphoria is a term that was coined by Dr. William Dodson to describe the phenomenon of rejection sensitivity in ADHD sufferers. It does not appear to be a 'valid' term, in the sense that there is no DSM definition. In fact, it seems that Dodson himself is the only one to have used the term. Dodson ...

The problem with ADHD is that it doesn't really have its own trademark indicator, the way that schizophrenia might or Aspberger's might. There are several different subtypes of ADHD, and they tend to look different from each other, particularly in the instance of ADHD with hyperactivity and ADHD-PI (primarily inattentive). Even then, there are plenty of ...

Different diagnostic systems may assign these syndromes to different categories based on theory or clinical opinion. In the DSM-IV era, OCD was listed under the "Anxiety disorders" category; however, in the DSM-5, it is now listed under a different "Obsessive-Compulsive and related disorders" category. ADHD is currently under the "Neurodevelopmental ...

The difference is in consistency. Bipolar disorder there is usually episodic; quick, drastic changes between normality, mania, depression and anger. ADHD on the other hand is chronic and affects attention and behavior rather than mood. Anger is of course a symptom but usually only situational. Over a period of time, bursts of anger and other moods can be ...

Actually,if you saw a few of Dr. Barkley's presentations. He referred to people with autism spectrum disorder as hyperfocus because they focused immensely on fine details of their sensations and their environments. While this hyperfocus, lacks the big picture perception. For instance, the child with autism might focus on the car wheel, while not attending to ...

Alright- neurodiversity vs neurotypical label aside, here is the definition of ADHD http://www.cdc.gov/ncbddd/adhd/diagnosis.html Here is the best example I could find which demonstrates effect of ADHD on mathematical reasoning: http://ldq.sagepub.com/content/16/1/6.short Here is a comparison between learners who are nonverbal, who have aspergers, and ...

If you don't focus, then your efficiency easily drops to 50% of other people. But if the task is truly engaging you, you work 200% compared to other people and you forget everything else. This has a name: Hyperfocus! Like distractibility, hyperfocus is thought to result from abnormally low levels of dopamine, a neurotransmitter that is particularly ...
