Cognitive disorders are a category of mental health disorders
that primarily affect learning, memory, perception, and problem solving, and include amnesia, dementia, and delirium. With age, other conditions such as stroke, dementia, delirium, brain tumors, chronic alcohol use or abuse, substance abuse, some vitamin deficiencies, and some chronic diseases
may cause cognitive impairment. Warning Signs of Mild Cognitive Impairment. People with mild cognitive impairment
are more forgetful than normal for their age, but they don't experience other cognitive problems associated with dementia, such as disorientation or confusion about routine activities. Doctors often assess mental performance with a brief test such as the Mini-Mental State Examination (MMSE). More-detailed neuropsychological testing may help determine the degree of memory
impairment, which types of memory
are most affected and whether other mental skills also are impaired.
