Alzheimer’s Disease Overview

ICD-10 Code 

  • G30 - Alzheimer's disease

Alzheimer’s Disease Etiology and Epidemiology 

Alzheimer’s disease is a progressive neurological disorder and the most common cause of dementia. It is characterized by a continuous decline in cognitive, behavioral, and social skills, which affects a person's ability to function independently (Honig et al., 2018). The disease causes brain shrinkage and neuronal cell death. 

Alzheimer’s Disease Prevalence: 

  • Approximately 7 million people in the U.S. have Alzheimer’s disease, with 73% being 75 years or older. 
  • Of the 55 million people living with dementia globally, over 60% are estimated to have Alzheimer’s disease. 

Alzheimer’s Disease Symptoms: 

  • The primary sign is memory impairment, particularly the inability to recall conversations or recent events.  
  • As the disease progresses, individuals experience debilitating memory loss and a reduced ability to perform daily tasks (Aisen et al., 2017). 

Diagnosis 

Diagnosis involves gathering information from family members and performing various tests (Canter, 2016): 

History: 

  • Medical history 
  • Use of over-the-counter medications (including vitamins, herbs, etc.) 
  • Diet 
  • Ability to perform activities of daily living (ADLs) 
  • Changes in personality or behaviors 

Memory Tests: 

  • Assess attention, counting, language, and problem-solving skills 

Diagnostic Tests: 

  • Blood and urine tests to rule out other medical problems 
  • CT scan 
  • MRI and PET scans to rule out other medical issues 

Definitive Diagnosis: 

  • Alzheimer's can only be definitively diagnosed post-mortem through brain tissue examination during an autopsy. 

Management 

There is no cure for Alzheimer’s disease. Therefore, management focuses on: 

Goals: 

  • Improving or maintaining quality of life 
  • Enhancing cognition, mood, and behavior 
  • Promoting a safe environment 
  • Encouraging social engagement 
  • Maintaining daily functioning 

Treatment: 

  • Medications can temporarily slow disease progression and alleviate symptoms, helping to improve or maintain independence for a time.  
  • Support programs are available for patients and their families.
