Dementia, a syndrome of acquired intellectual deterioration, is an etiologically nonspecific condition that can be permanent or reversible. When evaluating demented patients, a careful exposure history will determine the possible role of drugs, metals, or toxins. Physical examination may reveal focal deficits in cases of intracranial mass lesions and spasticity or ataxia of the lower limbs if hydrocephalus is present. Coexistence of dementia and a peripheral neuropathy usually indicates the existence of a toxic or metabolic disorder. Depressed mood, sleep disturbance, anorexia, impotence, constipation, and psychomotor retardation indicate the presence of a depressive syndrome. Asterixis, myoclonus, and postural tremor are common in toxic-metabolic dementias, whereas resting tremor, choreoathetosis, or rigidity occur in progressive extrapyramidal disorder. EEG is focally abnormal in cases of cerebral mass lesions and shows generalized slowing in toxic-metabolic encephalopathies. CT will aid in the identification of hydrocephalus, subdural hematomas, and intracranial mass lesions. A thorough laboratory evaluation including complete blood count, erythrocyte sedimentation rate, electrolytes, blood urea nitrogen and blood sugar, liver and thyroid function tests, serum calcium and phosphorus levels, B12 and folate levels, serum copper and ceruloplasmin, VDRL, chest X-ray, electrocardiogram, and lumbar puncture may demonstrate treatable disorders that are adversely affecting intellectual function. Elderly individuals are particularly susceptible to the effects of toxic or metabolic disorders, and a mild dementia may be exaggerated by relatively minor fluctuations in metabolic status. Treatable causes of dementia should be sought in all demented patients.

Primary hemochromatosis is characterized by a specific pattern of clinical manifestations. It includes liver disease with hepatomegaly, glucose intolerance, e.g. diabetes, hyperpigmentation oft the skin, impotence/ amenorrhea, arthropathy, cardiomyopathy and fatigue. Laboratory investigation reveals significantly elevated serum ferritin and transferrin saturation with iron. The diagnosis is confirmed by liver biopsy and quantitative determination of elevated liver iron content. Wilson's disease represents a copper storage disease. Prominent clinical features are hepatomegaly and splenomegaly. Neurological alterations and detection of Kayser-Fleischer corneal rings are typical. In the acute initial phase the often young patients present with Coombs-negative hemolysis. Psychiatric alterations, cardiomyopathy, arthropathy, nephropathy, as well as thrombocytopenia and leucopenia are other clinical features. Laboratory parameters of Wilson's disease include low serum ceruloplasmin and serum copper. There is an elevated urinary copper excretion and elevated serum free copper concentration. The diagnosis is confirmed by liver biopsy with quantitative determination of an elevated liver copper content.
