1. The four major categories of cognitive disorders are: delirium which is an alteration in consciousness that manifest and progresses over a relatively short span of time where people have a decreased cognizance of their surrounding environment; dementia is an on-going atrophy of brain function that is pronounced by damage of memory, bewilderment and inability to focus; amnesia marked by an indicative loss of memory, against no loss of other cognitive functions that appear in dementia; there is also an inclusion of other cognitive disorders not particularly specified that may otherwise not be categorized properly on their own. A broad assortment of factors may lead to cognitive disorders, that could also encompass other general medical conditions such as brain infections or head injuries. Cognitive disorders are normally assessed after physical and neurological inspection. Examples of these tests would be imaging exams, blood screening, liver function tests and thyroid analysis. Treatment options vary and depend on what kind of condition appears. Delirium for instance is normally treated adequately through analysis of the underlying cause, the prognosis however, is not as positive for patients suffering from dementia or amnesia. Common mental disorders such as depression, affect cognitive functions, through the process of memory as well perception and problem solving. As mentioned for the fourth category, other cognitive disorders make up this section. Berkman &
