Abstract:
Subjective cognitive impairment or SCl is frequent (50% of the population after 50 years of age) and corresponds to numerous etiologies. To diagnose the etiology of a SCI, one must refer to the specific cognitive stage impaired (registration, storage, and retrieval) and use specific tests that may resolve the issue. The possibility of a neurodegenerative disorder as a cause of SCI must lead to caution. Paraclinical and complete neuropsychological testing is required as soon as this etiology s possible after an initial neurological consult.
