Dementia is a clinical syndrome characterized by multiple, acquired and persistent cognitive deficits, capable of substantially interfering in the patient’s activities of daily living. The diagnosis of Dementia with Lewy Bodies (LBD) is characterized by fluctuation in cognitive functions, recurrent, well-formed, and detailed visual hallucinations, and parkinsonism, with stiffness, tremor, bradykinesia, and slurred speech. Our goal is to describe a case report of LBD that for several years was diagnosed and treated as depression. It is extremely important to have detailed medical research in these cases, including performing differential diagnosis with depression, in order to enable adequate treatment, family guidance and receipt of financial benefits provided by government authorities.
