Shunt-responsive dementing illness in a Nigerian--a case report.

Dementia is a growing medico-social problem worldwide because of the rising population of the elderly. About 10-30% of the cases have been found to be treatable or reversible with the improvement in neuro-diagnostic and neuro-imaging techniques. These reversible cases should be diagnosed without over-investigating the many patients with irreversible disease. We present a case of a reversible dementia due to Normal Pressure Hydrocephalus with dramatic surgical therapeutic response.
