• No severe hearing and/or visual impairments, neurodevelopmental, or psychomotor disorders.
• No brain injuries that may interfere with cognitive functions (history of traumatic brain injury with parenchymal injury or macroscopic ischemic stroke of large extra-axial vessels or hemorrhagic stroke, brain surgery, brain tumors, or other causes that could result in acquired brain damage such as brain chemotherapy or radiotherapy).
• No treatment with antipsychotic agents in the 6 months prior to the initial assessment.
• No medical condition requiring chronic systemic medication with psychoactive effects causing confusion. No psychiatric or neurological medication.
• No alcohol or drug abuse.
• No serious health problems in the last 12 months (especially neurological or cardiac disorders).
• Diagnosis of Alzheimer's type dementia, based on a clinical and cognitive assessment conducted by a physician.
• Diagnosis of vascular or mixed type dementia, based on a clinical and cognitive assessment conducted by a physician.
• Lack of autonomy in: 1. basic activities according to the Barthel Index; 2. instrumental activities according to the Lawton Index. Both indices assess dependence associated with the diagnosis of dementia, distinguishing it from the diagnosis of mild cognitive impairment.
• Diagnosis of mild cognitive impairment, based on a clinical and cognitive assessment conducted by a physician.
• Preserved autonomy in: 1. basic activities according to the Barthel Index; 2. instrumental activities according to the Lawton Index. Both indices assess dependence associated with the diagnosis of dementia, distinguishing it from the diagnosis of mild cognitive impairment
