Hyperactivity has long been part of the human condition, although hyperactive behaviour has not always been seen as problematic. [1] [page needed]The terminology used to describe the symptoms of attention deficit hyperactivity disorder, or ADHD, has gone through many changes over history, including "minimal brain damage", "minimal brain dysfunction", "learning/behavioral disabilities" and ...
The brain of Albert Einstein has been a subject of much research and speculation. Albert Einstein 's brain was removed within seven and a half hours of his death. His apparent regularities or irregularities in the brain have been used to support various ideas about correlations in neuroanatomy with general or mathematical intelligence.
This condition later became known as attention deficit hyperactivity disorder (ADHD). Its symptoms were first described by German doctor Melchior Adam Weikard in 1775. The concept of child hyperactivity or hyperkinetic behaviour became established in the United States in the 1930s. Around 50-70% of people with ASD also have ADHD. [204]
A late talker is a toddler experiencing late language emergence (LLE), [2] [3] which can also be an early or secondary sign of an autism spectrum disorder, or other developmental disorders, such as fetal alcohol spectrum disorder, attention deficit hyperactivity disorder, intellectual disability, learning disability, social communication disorder, or specific language impairment.
Clinically significant symptoms of these two conditions commonly co-occur, and children with both sets of symptoms may respond poorly to standard ADHD treatments. Individuals with autism spectrum disorder may benefit from additional types of medications. [13] [14] The term AuDHD is sometimes used for those with both autism and ADHD.
] Children with ADHD have worse educational outcomes [21] and a higher risk of unintentional injuries. [256] In adults, hyperactivity is often replaced by inner restlessness, and adults affected are likely to develop coping mechanisms as they mature, thus compensating to some extent for their previous symptoms. [22] [222]
The prevalence of ADHD within the age group of 5-11 years for both male and female children is 8.6%, whereas children in the age group of 12-17 years is 14.3%. [ 37 ] This difference between genders may reflect either a difference in susceptibility or that females with ADHD are less likely to be diagnosed than males. [ 38 ]
(Einstein was formally awarded his PhD on 15 January 1906.) [79] [80] [81] Four other pieces of work that Einstein completed in 1905—his famous papers on the photoelectric effect, Brownian motion, his special theory of relativity and the equivalence of mass and energy—have led to the year being celebrated as an annus mirabilis for physics ...
