Features of Alzheimer include all except
**Core Concept**
Alzheimer's disease is a progressive neurodegenerative disorder characterized by cognitive decline, memory loss, and eventually, dementia. The pathophysiology involves the accumulation of amyloid-beta plaques and tau protein tangles in the brain, leading to neuronal loss and synaptic dysfunction.
**Why the Correct Answer is Right**
Medications for Alzheimer's disease, such as cholinesterase inhibitors (e.g., donepezil) and memantine, can temporarily improve symptoms by increasing acetylcholine levels and blocking N-methyl-D-aspartate (NMDA) receptors. However, these medications do not offer a near 100% cure for the disease, as they only slow down the progression of symptoms. The underlying pathology of amyloid-beta accumulation and tau protein tangles remains unaddressed.
**Why Each Wrong Option is Incorrect**
**Option A:** Alzheimer's disease is actually more common in males than females, with a male-to-female ratio of approximately 1.2:1 in the general population.
**Option B:** Recent memory loss is a hallmark feature of Alzheimer's disease, as affected individuals often struggle to recall new information and form memories.
**Option C:** The Mini-Mental State Examination (MMSE) is a widely used screening tool for cognitive impairment and dementia, including Alzheimer's disease. It assesses various cognitive domains, such as orientation, memory, attention, and language.
**Clinical Pearl / High-Yield Fact**
Alzheimer's disease is a heterogeneous disorder, and not all patients exhibit the same symptoms or rate of progression. Clinicians should be aware of the different subtypes of Alzheimer's, including early-onset and late-onset forms, as well as the presence of comorbidities, such as vascular dementia or Lewy body dementia.
**Correct Answer:**
β Correct Answer: D. Medications offer near 100% cure
