Understanding Alzheimer's Disease: Stages, Causes, Symptoms, and Management

Alzheimer's disease is a neurological condition that progressively damages brain cells, leading to memory loss and cognitive decline. Predominantly affecting older adults, this condition is also known as dementia. Currently, approximately 80% of the population is impacted by Alzheimer's, and this number is projected to double by 2050. Early symptoms are often subtle, making diagnosis difficult, but as the disease advances, the severity increases significantly.

Alzheimer’s Disease Overview
Alzheimer's progresses through distinct stages, including:
  • Preclinical stage
  • Mild cognitive impairment
  • Dementia
Furthermore, the disease can be categorized into seven stages based on symptom severity.

What Causes Alzheimer’s?

The primary cause involves malfunctioning brain cells. Over time, nerve cells deteriorate and die, leading to reduced brain tissue. Autopsies reveal that affected individuals have fewer nerve cells and deposits called plaques and tangles, primarily composed of beta-amyloid and tau proteins. While the exact cause remains unclear, risk factors include:

  • Family history
  • Advanced age
  • Specific genetic markers
  • Poor cardiovascular health

Recognizing Symptoms

Early detection is vital for managing Alzheimer's. Common signs include:

  • Difficulty remembering recent information
  • Problems recognizing familiar faces
  • Speech hesitation and reading or writing issues
  • Behavioral changes such as apathy and social withdrawal
  • Poor judgment and problem-solving skills

Available Treatments

While no cure exists, therapies aim to slow progression. Medications like tacrine, donepezil, and rivastigmine can reduce symptoms, and NMDA receptor antagonists may be prescribed if needed. Additionally, engaging in group and cognitive activities can help maintain brain function and delay symptom severity.
