Self-stimulatory behavior, also known as "stimming" [1] and self-stimulation, [2] is the repetition of physical movements, sounds, words, moving objects, or other behaviors. Stimming is a type of restricted and repetitive behavior (RRB). [3] Such behaviors (also scientifically known as "stereotypies") are found to some degree in all people, but ...
Stimming has many forms, some quite adaptive and others maladaptive (for example, excessive hand-wringing can injure joints, and excessive rubbing or scratching of skin can injure it). Another form of self-treatment that arises not uncommonly is self-medication , which unfortunately can lead to substance use disorders such as alcohol use disorder .
Punding has been linked primarily to an imbalance in dopamine D1 receptor and D2 receptors activation within the cortico-basal-ganglia-thalamo-cortical loop, [9] which has been proposed to lead to substantial changes in the striatum (especially its dorsal and ventral areas) and the nucleus accumbens, some of the main dopaminergic areas of the brain regulating psychomotoric functions and reward ...
Stereotyped movements are common in infants and young children; if the child is not distressed by movements and daily activities are not impaired, diagnosis is not warranted. [1] When stereotyped behaviors cause significant impairment in functioning, an evaluation for stereotypic movement disorder is warranted.
Tics must be distinguished from movements of disorders such as chorea, dystonia and myoclonus; the compulsions of obsessive–compulsive disorder (OCD) and seizure activity; [6] and movements exhibited in stereotypic movement disorder or among autistic people (also known as stimming).
A 2016 survey in the United States reported a rate of 25 per 1,000 children for ASD. [375] Rates of autism are poorly understood in many low- and middle-income countries, which affects the accuracy of global ASD prevalence estimates, [ 376 ] but it is thought that most autistic people live in low- and middle-income countries.
Rett syndrome (RTT) is a genetic disorder that typically becomes apparent after 6-18 months of age and almost exclusively in girls. [4] Symptoms include impairments in language and coordination, and repetitive movements. [4]
Gratification disorder is a rare and often misdiagnosed form of masturbatory behavior, or the behavior of stimulating of one's own genitals, seen predominantly in infants and toddlers. [1] Most pediatricians agree that masturbation is both normal and common behavior in children at some point in their childhood.
