  1. Numerous significant correlations were presented between test scores measuring cognitive performance and motor actions, while there was no significant correlation among movements and neuropsychiatric properties including mood and anxiety measurements. *Indicates significant correlation (p < 0.05).
  2. 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-S: Spielberger State and Trait Anxiety Inventory Trait Score.
  3. aLower score associates with better cognitive performance.
