#memory loss

• Alzheimer's — The name of a progressive and irreversible neurodegenerative disease, representing the most common cause of dementia in older adults, clinically characterized by memory loss, severe cognitive decline, and behavioral changes; a medical eponym structurally named in honor of the German psychiatrist and neuropathologist Alois Alzheimer. This condition is pathologically marked by the accumulation of beta-amyloid plaques and neurofibrillary tangles in brain tissue, leading to neuronal destruction and cortical atrophy.
• Amnestic — Pertaining to amnesia, causing memory loss, or characterized by severe impairments in the consolidation and recall of memories. In a clinical and neuropsychological sense, it describes a structural syndrome or a pharmacological side effect that affects brain circuits responsible for short-term or long-term information storage, without necessarily altering other higher cognitive functions.
• Amnesic — The feminine form of 'amnezic'; describes a female person, a clinical state, or a pharmacological reaction characterized by the total or partial loss of the ability to store, consolidate, or recall memories. In a structural neuropsychological sense, the amnestic manifestation can occur as a direct consequence of hippocampal lesions, intense emotional trauma, or as a temporary side effect of sedative substance administration.
• Amnesia — The total or partial loss of memory, caused by organic factors (head trauma, stroke, neurodegenerative diseases) or psychogenic factors (severe emotional shocks, psychological trauma). Structurally, the condition is classified into anterograde amnesia (inability to form new memories) and retrograde amnesia (inability to recall events prior to the onset of the disease), affecting the patient's quality of life and autonomy.
