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 ...

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 I'll cite parts of the abstract, starting with But analyses of the published data and the unpublished data that were hidden by drug companies reveals that most (if ...

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 ...

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 ...

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", "mania",...

They are interchangeable. ADD was a term used throughout most of the 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 ...

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 ...

Why the symptoms were picked out and given a name Professionals used to believe ADHD was something children grew out of, but not anymore. ADHD has always been strongly related to school performance. If a child is not focused on school, and seems unwilling or unable to concentrate, everyone tends to think of ADHD as the cause. This makes me think that ADHD ...

The problem with ADHD is that it doesn't really have its own trademark indicator, the way that schizophrenia or Asperger'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 disorders ...

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 ...

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 in ...

You might want to look at Bondü, R. & Esser, G. Eur Child Adolesc Psychiatry (2015) 24: 185. https://doi.org/10.1007/s00787-014-0560-9 The authors found fairly compelling evidence of a latent construct of rejection sensitivity associated with ADHD in a large (>1200) German sample of adolescents. This existed independently of another interesting ...

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 ...

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 ...

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 ...

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 ...

Borderline Personality Disorder (BPD) is a complicated diagnosis to understand and treat. A painful mix of emotional trouble, unstable relationships and self-destructive behavior, including suicide attempts are associated with BPD. Experts have given a new name to BPD as Biosocial disorder. People who develop BPD are highly emotional, sensitive and reactive,...

Dodson distinguishes "RSD" from social anxiety in that the latter begins as an anticipatory fear and is generally lessened upon social interaction whereas the RSD flare-ups begin as in-the-moment perceptions of an important social rejection and have emotional consequences that unfold from there. (See this slideshow and accompanying video.) I do not believe ...

IQ in ADHD sufferers indeed increases with the treatment of stimulants, such as methylphenidate (Meyes et al., 1994). This is thought to rely on the attention-narrowing effect of stimulants, i.e., they cause the easily distracted ADHD child to focus better on the IQ task (Aman, 1996). It is an interesting question indeed whether such an effect also plays ...

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 best-...

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 ...

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 ...

The approach you would take will depend upon your level of analysis. For instance, one could choose to model an entire individual's behaviour (i.e. with heuristic models), the activity of neural circuits, the activity of a subset of neural populations, etc. By your question including traits such as "impulsivity," I will assume that you are looking to model ...

I understand ADHD is a standard term, but I'm still a bit suspicious that it's not a useful one; Psychiatry doesn't seem like the most reliable field Okay, I know this is going to sound weird, but I think ADHD is another name for hypofrontality-mediated unfulfilled potential ADHD as "unfulfilled potential" Although it is characterised by a dysregulation ...

ADHD used to be called just ADD in DSM-III (released in 1980), with the subtypes ADD/H (ADD with hyperactivity) and ADD/WO (ADD without hyperactivity). However, by 1987 when DSM-III-R was published, it turned out there was not enough empirical evidence to support the multidimensional view of ADD from DSM-III, so DSM-III-R adopted a unidimensional view, which ...

Attention Deficit Hyperactivity Disorder (ADHD) is a type of Neuro-developmental condition whose signs can be seen during early childhood. ADHD is related to hyperactive behavior, attention difficulties or difficulty in controlling behavior. ADHD can affect an individual’s ability, whether at school or work depending on the symptoms. Usually, the majority ...
