Clinical Manifestation of Dementias

Symptoms of dementia vary widely according to the etiology, nature, progression of the causative disease. Not only various cognitive and non-cognitive features are present in any given point of evaluation, but also it is very common to note the ups and downs of such symptoms in an individual patient as the disease progress. Although cortical degenerative dementia such as Dementia of Alzheimer's Type typically show cognitive deficit in language, memory, praxis etc. in its early stage, it is unwise to confine such symptoms to be characteristic only in cortical dementias. Likewise, neurologic symptoms or changes in affect, personality and behavior, frequently seen in vascular dementia or other subcortical degenerative dementias should be understood as a part of whole cognitive and behavioral symptomatic gamut. As a logical conclusion, when evaluating the symptoms of a dementic patient, all the physical, neurologic, and neuropsychiatric evaluation must be applied as well as neuropsychological assessments. In addition, attention must be paid on the patients' functionality of daily living, reversibility, and appropriateness of services by family members or caregivers.
