Psychiatric diagnoses are frequent in memory units, but most neurologists do not feel comfortable about making the diagnosis of psychopathologic cognitive complaint or disorder. The full diagnosis usually requires careful history taking and a neuropsychological examination followed by a clear joint explanation to the patient. There are no good validated clinical signs to distinguish organic memory complaints from psychological disorders, but a nonorganic pattern, as seen in somatic conversion disorder, can be suggestive of a "cognitivoform" disorder. ⋯ The neurologist can rule out organic disorders or an exaggeration of somatic symptoms and determine the precise etiology in order to build a rationale for treatment. The neurologist can also avert an overconsumption of complementary explorations. In conclusion, this study shows first that psychopathologic disorders are commonly encountered in a neurological memory unit, emphasizing the need for training for the neurologist and collaboration with a psychiatrist, and secondly that the role of the memory unit cannot be limited to the diagnosis of Alzheimer's disease.
