Cognitive impairment occurs when problems with thought processes occur. It can include loss of higher reasoning, forgetfulness, learning disabilities, concentration difficulties, decreased intelligence, and other reductions in mental functions.
Cognitive impairment can be the result of several causes such as genetic syndromes, malnutrition, prenatal drug exposure, hypoglycemia, trauma or child abuse, and oxygen deprivation in the womb during or after birth among other reasons.
