Kleptomania -an impulse control

Kleptomania is an impulse control disorder often related to other mood disorders, such as depression, substance abuse, or eating disorders. But not everyone who shoplifts is a kleptomaniac.

Kleptomaniacs do not steal because they want a particular item and can't afford it. In fact, they often discard stolen items, or secretly return them to the store from which they were taken. Instead, kleptomaniacs are driven by an uncontrollable urge to steal things. They often feel increased anxiety when the craving hits, and this can only be relieved by taking the desired item. Often they are not even fully aware that they have stolen the item.

Ataxia-telangiectasia


Ataxia-telangiectasia (AT) (Boder-Sedgwick syndrome or Louis-Bar syndrome is a rare, neurodegenerative, inherited disease which affects many parts of the body and causes severe disability. Ataxia refers to poor coordination and telangiectasia to small dilated blood vessels, both of which are hallmarks of the disease.

AT affects the cerebellum (the body's motor coordination control center) and also weakens the immune system in about 70% of the cases, leading to respiratory disorders and increased risk of cancer. It first appears in early childhood (the toddler stage) with symptoms such as lack of balance, slurred speech, and increased infections. Because all children at this age take time to develop good walking skills, coherent speech, and an effective immune system, it may be some years before AT is properly diagnosed.

Cephalic disorders


Cephalic disasters (from the Greek word κεφάλη, meaning "head") are congenital conditions that stem from damage to, or abnormal development of, the budding nervous system. Cephalic is a term that means "head" or "head end of the body."

Cephalic disorders are not necessarily caused by a single factor, but may be influenced by hereditary or genetic conditions, nutritional deficiencies, or by environmental exposures during pregnancy, such as medication taken by the mother, maternal infection, or exposure to radiation (such disorders are more common in areas of the former Soviet Union affected by nuclear waste disposal problems, such as the area around the Mayak plant in Chelyabinsk, Russia.) Some cephalic disorders occur when the cranial sutures (the fibrous joints that connect the bones of the skull) join prematurely. Most cephalic disorders are caused by a disturbance that occurs very early in the development of the fetal nervous system.
