Neuropsychological Indicators of SCD Progression (SCD-CI)

In Individuals With Subjective Cognitive Decline, Age, Memory and Action Speed Scores at Baseline Predict Progression to Cognitive Impairment

Some patients with subjective cognitive decline (SCD) progress to neurocognitive disorders (NCD), whereas others remain stable; however, the neuropsychological determinants of this progression have not been identified. The investigators objective was to examine baseline neuropsychological indicators that could discriminate between people in whom the SCD progressed to a mild or major NCD and people in whom the SCD remained stable.

The investigators retrospectively included patients consulting for SCD at a university medical center's memory center (Amiens, France) and who had undergone three or more neuropsychological assessments at least 6 months apart. The relationship between domain-specific scores and the global cognitive score (GCS, as a function of final status (stable SCD vs. progression toward a mild or major NCD)) was examined using a generalized linear mixed model.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Variation of neuropsychological indicators (global congnitive score) between NCD et SCD patients
Time Frame: one year

subjective cognitive decline (SCD) neurocognitive disorders (NCD) neuropsychological indicators could discriminate between people in whom SCD progressed to a mild or major NCD and people in whom SCD remained stable.

A global cognitive score was created using all 5 tests : Alice Heim 4-I tests inductive reasoning ; Short-term verbal memory was assessed with a 20-word free-recall test; Two measures of verbal fluency were used: phonemic and semantic; Vocabulary was assessed using the Mill Hill Vocabulary test.
