Figure 2

Corrgram between hand movement parameters and neuropsychological test results. Blue color indicates negative correlations, while red demonstrates positive correlations. A clear trend is visible, patients with lower cognitive scores in MMSE, ACE, RAVLT have higher movement values (negative r). However, lower cognitive scores are also indicated with higher TMT and CDR scores, where mouse movements show also higher values (positive r). In conclusion, increase in motor parameters indicates worse cognitive performance. Highest r values are presented in time of left-hand movements. A trend is also visible for higher r values of other movement parameters in case of the left hand. MMSE Mini-Mental State Examination, ACE Addenbrooke Cognitive Examination, RAVLT Rey Auditory Verbal Learning Test, TMT Trail-Making Test, CDR Clinical Dementia Rating scale, BDI Beck Depression Inventory, STAI-S Spielberger State and Trait Anxiety Inventory State Score, STAI-T Spielberger State and Trait Anxiety Inventory Trait Score.
