A
lzheimer’s disease is a most common dementia in the world. Approximately 30% of the population over the age of 80’s
will present it. Although it is a disease with the well-defined diagnostic criteria, the exclusion of other diseases is very
important. The physician should present in his mind the arsenal of differential diagnoses of main clinical features of each
disease that potentially mimics an alzheimer’s disease, thus facilitating the identification of them. In this heterogeneous group
of dementias, curiously found some of them that are potentially reversible. In the group of dementias, we found primary and
secondary diseases as cause of dementia process: Deficiency of vitaminB12, B1, tertiary syphilis, normal pressure hydrocephalus,
brain tumors, vascular dementia, delirium, depression, Lewy body disease, Central Nervous System (CNS) vasculitis, fronto-
temporal dementia, drug intoxication and Parkinson's disease, although the technology evolution, many of the aforementioned
diagnosis may be performed based on the patient’s medical history and physical examination. Patients with reports of sadness
and loss of energy may suggest the diagnosis of depression in an elderly patient with cognitive impairment. Cognitive changes
initiated abruptly suggest more the diagnosis of delirium than dementia. In these cases, a secondary etiology needs more
investigation. The history of daily alcohol consumption may suggest deficiency of vitamin B1 (Korsakoff syndrome). Young
patients with arthralgia, weight loss and rash are associated with CNS vasculitis. Changes in gait, urinary incontinence are
common findings in normal pressure hydrocephalus. Patients with reports of recurrent strokes may have vascular dementia.
Motor changes such as spasticity is associated to dementia by Lewy bodies and Parkinson’s disease in a late stage. It is concluded
that anamnesis and physical examination is considered the initial step in the investigation of a patient who comes at the office
with a complaint of memory problems.
