Neurocognitive Disorders

Neurocognitive Disorders, previously referred to as dementia, constitute a spectrum of conditions marked by cognitive deterioration significant enough to impede daily functioning. Alzheimer's disease, vascular dementia, Lewy body dementia, and frontotemporal dementia are prevalent forms of NCDs, each characterized by distinct pathological traits and clinical manifestations. These disorders stem primarily from neurodegenerative processes, cerebrovascular complications, or other cerebral pathologies. Symptoms encompass memory loss, executive dysfunction, language impairments, visuospatial challenges, and alterations in mood or behavior. The neurobiological underpinnings involve progressive neuronal loss, synaptic dysfunction, aberrant protein aggregation like amyloid-beta plaques and tau tangles, and neuroinflammation. Genetic predispositions, environmental factors, and lifestyle choices also contribute to NCD onset and progression. Timely diagnosis and intervention are pivotal for NCD management, though treatment options remain somewhat limited. Therapeutic strategies focus on symptom alleviation, cognitive stimulation, pharmacotherapy targeting neurotransmitter systems, and addressing modifiable risk factors such as hypertension, diabetes, and sedentary lifestyle. Moreover, providing supportive care and educating caregivers constitute vital aspects of NCD management to enhance patients' quality of life.
