Is Low Psychomotor Speed a Marker of Brain Vulnerability in Late Life? Digit Symbol Substitution Test in the Prediction of Alzheimer, Parkinson, Stroke, Disability, and Depression.

CONCLUSION: Low psychomotor speed is associated with an increased risk of developing various brain outcomes: dementia, AD, PD, disability, depressive symptoms, and marginally stroke. Low psychomotor speed may be the consequence of a number of discrete cerebral abnormalities and could be considered as a marker of brain vulnerability. In clinical practice, a low score in DSST should be seen as a warning sign of possible negative evolution. PMID: 31466055 [PubMed - as supplied by publisher]
