Clinical Trials Detalhe

Alzheimer's disease (AD) is the most common of dementia, and has associated cognitive and motor disorders, with consequences on daily activities, including handwriting. Handwriting has been used to study fine motor control or executive functioning in healthy and unhealthy populations. Changes in this skill are present at different stages of the clinical course of Alzheimer's Disease. The sensorimotor deterioration is observed in handwriting tasks (motion kinematics, such as movement time, speed, and profiles) and brain activity rhythms. Handwriting has been used to study fine motor control or executive functioning in healthy and unhealthy populations, and changes in this skill are present at different stages of the clinical course of dementia. From a theoretical perspective, because sensorimotor deterioration observed in handwriting tasks (motion kinematics, such as movement time, speed, and profiles). Due to the large number of brain areas related to handwriting performance, brain electrical activity analysis can be an early indicator of brain dysfunction. Although there is a lack of validation across healthy and non-healthy populations Electroencephalogram (EEG) measures have the potential for evaluating cognitive performance. This research aims to analyze the suitability of the handwriting assessment protocol, which can contribute to a more in-depth knowledge of this subject and potentially support early identification and treatment.

Dementia

Dementia group Inclusion criteria: * Over 50 years of age * The inclusion criteria for the dementia group are as follows: patients diagnosed with dementia according to the DSM-5 criteria and cognitive impairment proven in the neuropsychological assessment * Portuguese native language Exclusion criteria: \- Previous neurological history (e.g. stroke, traumatic brain injury, multiple sclerosis, among others), psychiatric history or other incapacitating illnesses that could interfere with the collection of writing data. (NOTE that neurological disease is accepted in the dementia group, but co-morbidity of previous and actual neurological diseases will be excluded) Cognitively normal group Inclusion criteria: * Over 50 years of age * At least three years of schooling Exclusion criteria: \- Presence of neurological history (e.g., stroke, traumatic brain injury, multiple sclerosis, among others), psychiatric history, or other incapacitating illnesses that could interfere with the collection of writing data.
