Quick Answer
Alzheimer's disease is the most common cause of dementia, characterized by progressive memory and functional decline due to neurodegenerative changes. Dr. Jitendra Prasad Yadav (NMC 8029, 15+ years of clinical experience) evaluates alzheimer's disease at Kathmandu Neurology Clinic & Cognitive Center, Durbar Marg, Opposite of Yak & Yeti Hotel, Kathmandu 44600, Nepal — evidence-based, medically reviewed.
Early changes often involve short-term memory and word finding, with gradual impact on independence. Biomarker, imaging, and clinical correlation may support diagnosis in appropriate settings.
Clinical evaluation, cognitive testing, informant history, imaging, and lab review; biomarker testing is selective and specialist-guided where available.
No curative treatment; focus on education, planning, caregiver support, comorbidity management, and discussion of supportive options appropriate to stage.
Management is individualized and discussed with benefits, limitations, and follow-up.
No proven prevention; brain-health measures may support general health but do not guarantee avoidance.
No; while age is a risk factor, not all older adults develop Alzheimer's.
No proven prevention exists. Brain-health measures (cognitive engagement, exercise, cardiovascular health, good sleep) may support general health but do not guarantee avoidance.
Alzheimer's is the most common cause of dementia but is not the only cause. Specialist evaluation helps identify the underlying type.
Progression varies; some people have rapid decline, others progress slowly over many years. Predictability is limited.
Some options exist that may slow decline in certain stages, but no cure is available. Specialist assessment determines if any are appropriate.
Parkinson's disease is a progressive movement disorder associated with dopaminergic system changes, causing tremor, slowness, stiffness, and balance issues.
Dementia involves progressive decline in memory, thinking, behavior, or function that interferes with daily life, with many underlying causes.
