OCD affects roughly 1–⁠2% of adults (somewhat more women than men), and under 3% of children and adolescents.A person with OCD knows that the symptoms are unreasonable and struggles against both the thoughts and the behavior. Their symptoms could be related to external events they fear (such as their home burning down because they forget to turn off the stove) or worry that they will behave inappropriately.It is not certain why some people have OCD, but behavioral, cognitive, genetic, and neurobiological factors may be involved. Risk factors include family history, being single (although that may result from the disorder), and higher socioeconomic class or not being in paid employment. Of those with OCD about 20% of people will overcome it, and symptoms will at least reduce over time for most people (a further 50%). Selective mutism
Selective mutism (SM) is a disorder in which a person who is normally capable of speech does not speak in specific situations or to specific people. Selective mutism usually co-exists with shyness or social anxiety. People with selective mutism stay silent even when the consequences of their silence include shame, social ostracism or even punishment. Selective mutism affects about 0.8% of people at some point in their life.Testing for selective mutism is important because doctors must determine if it is an issue associated with the childs hearing, movements associated with the jaw or tongue, and if the child can understand when others are speaking to them.
Likewise, anxiety in children is sometimes misdiagnosed as attention deficit hyperactivity disorder or, due to the tendency of children to interpret their emotions physically (as stomachaches, headaches, etc. ), anxiety disorders may initially be confused with physical ailments.Anxiety in children has a variety of causes; sometimes anxiety is rooted in biology, and may be a product of another existing condition, such as autism spectrum disorder. Gifted children are also often more prone to excessive anxiety than non-gifted children. Other cases of anxiety arise from the child having experienced a traumatic event of some kind, and in some cases, the cause of the childs anxiety cannot be pinpointed.Anxiety in children tends to manifest along age-appropriate themes, such as fear of going to school (not related to bullying) or not performing well enough at school, fear of social rejection, fear of something happening to loved ones, etc. What separates disordered anxiety from normal childhood anxiety is the duration and intensity of the fears involved.
