Sintomatología obsesivo-compulsiva como precursora de un trastorno neurocognitivo

Abstract

Objective: to demonstrate how the use of the International Society to Advance Alzheimer's Research and Treatment (ISTAART) criteria for mild behavioural impairment (MBI) and also how the MBI-C Checklist can facilitate the early diagnosis of neurocognitive disorders. Clinical case: a 63 year-old patient, with an obsessive-compulsive disorder of 5 years onset. The negative progression, in spite of a correct treatment, led to the suspicion of a neurodegenerative process, regardless of a non-pathological cognitive screening and functional integrity. On further neuropsychological examination the clinical suspicion was confirmed. The use of the ISTAART criteria and the MBI-C Checklist is shown in order to clarify how its use can help to orientate a correct diagnosis. Results: an extensive neuropsychological examination confirmed the diagnosis of a neurocognitive disorder in this patient, and corroborates the usefulness of the MBI concept. Conclusions: the use of the MBI and MBI-C Checklist facilitates the diagnosis of neurocognitive disorders in their earlier stages, despite the apparent absence of cognitive or functional impairment.
