Basic Diagnostic Tests
Help rule out other conditions but are not specific for Alzheimer’s. They have low accuracy, detecting the disease less than 70% of the time.Electroencephalogram (EEG)- Non-invasive test that measures electrical activity in your brain.
- Uses small sensors called electrodes placed on your scalp.
- These electrodes record the brain's electrical signals.
- The procedure is painless and typically takes about 30 to 60 minutes.
Role of EEG in Alzheimer's Disease
- Diagnosis: EEG shows slower overall brain activity and reduced coherence between different brain regions.
- Monitoring Progression: EEG can track changes in brain activity over time.
- Differentiation: EEG can help differentiate Alzheimer's from other types of dementia or neurological conditions. This includes seizures and memory loss from liver and kidney disease.
Sensitivity

- Ability to correctly identify people who don't have ALZHEIMER'S 60% to 90%.
- All insurance cover this study for a diagnosis of Alzheimer's.
Magnetic Resonance Imaging (MRI)- Non-invasive imaging test.
- Uses powerful magnets to create detailed images of the brain.
- The procedure is painless.
In patients with Alzheimer’s disease, an MRI can detect changes in the brain such as shrinkage in specific areas like the hippocampus, which is crucial for memory.MRI can also help identify and exclude other potential causes of dementia symptoms, such as strokes, tumors, or fluid buildup (ventriculomegaly), ensuring a more accurate diagnosis.Sensitivity

Sleep
Sleep
Sleep affects memory, thinking, behavior.
Glymphatic System and Amyloid:
- The glymphatic system is a network in the brain responsible for clearing amyloid-beta, a protein linked to Alzheimer's disease.
- This system primarily operates during sleep, flushing out toxins and maintaining brain health.
- Impaired glymphatic function can lead to the accumulation of amyloid-beta
Importance of Sleep
- Cognitive Function: Essential for memory consolidation and cognitive processes.
- Brain Health: Clears out toxins, including beta-amyloid plaques during deep sleep.
Sleep Recommendations
- Sleep Duration: 7-9 hours of quality sleep per night.
- Consistency: Regular sleep schedule; same bedtime and wake time daily.
Diet and Sleep
- Healthy Eating: Balanced diet, avoid heavy meals close to bedtime.
- Avoid Alcohol: Can disrupt sleep patterns.
Sleep Disorders
- Sleep Apnea and Insomnia: Treat sleep disorders like sleep apnea and Insomnia
Lifestyle Tips
- Stress Management: Practice stress-reducing techniques.
- Daytime Naps: Limit to 20-30 minutes, early afternoon.

- Uses standardized tools to stage dementia (FAST, CDR)
- Reviews medications, especially high-risk ones
- Screens for behavioral symptoms like depression and anxiety
- Evaluates home and driving safety
- Identifies social support and caregiver readiness

Treat
FDA-approved medications and ongoing research trials for new treatments.
Very Early Disease
Early Disease Anti-Amyloid Antibody
Anti-amyloid antibodies are a class of drugs aimed at targeting and reducing amyloid plaques in the brain, a hallmark of Alzheimer’s disease. These therapies focus on slowing the progression of the disease by reducing the accumulation of amyloid-beta plaques.
Approved Anti-Amyloid Antibodies:
Aducanumab (Aduhelm)
- Developer: Biogen and Eisai
- Approval: FDA approved Aducanumab in June 2021 for the treatment of Alzheimer's disease.
- Mechanism: Aducanumab is a monoclonal antibody that targets aggregated forms of amyloid-beta, facilitating their removal from the brain.
- Efficacy: Clinical trials showed a reduction in amyloid plaques, though its effectiveness in slowing cognitive decline is debated. Approval was based on its ability to reduce amyloid-beta plaques rather than clear evidence of clinical benefit.
- Administration: Administered as an intravenous infusion once every four weeks.
- Controversy: The approval process was controversial due to mixed results in clinical trials and concerns about clinical efficacy and side effects.
Lecanemab (Leqembi)
- Developer: Eisai and Biogen
- Approval: FDA granted accelerated approval to Lecanemab in January 2023.
- Mechanism: Lecanemab binds to soluble amyloid-beta protofibrils, preventing plaque formation.
- Efficacy: Clinical trials indicated that Lecanemab reduces amyloid levels and shows some benefit in slowing cognitive decline.
- Administration: Administered via intravenous infusion every two weeks.
- Considerations: Approval was based on amyloid reduction, with ongoing studies required to confirm clinical benefits.
Donanemab
- Developer: Eli Lilly
- Approval: FDA granted approval to Donanemab in July 2024.
- Mechanism: Donanemab targets a modified form of amyloid-beta called N3pG, promoting plaque clearance.
- Efficacy: Studies show that Donanemab can reduce amyloid plaques and may slow the progression of cognitive symptoms in early-stage Alzheimer's patients.
- Administration: Administered as an intravenous infusion every 4 weeks.
- Considerations: Full clinical efficacy and long-term benefits are still being evaluated in ongoing trials.
Potential Side Effects
- Amyloid-Related Imaging Abnormalities (ARIA): Common side effect involving brain swelling and microhaemorrhages. Regular MRI monitoring is recommended.
- Infusion Reactions: Patients may experience reactions at the infusion site, including headache, dizziness, and nausea.
Importance of Monitoring
- Regular MRI Scans: To detect and manage ARIA.
- Cognitive Assessments: To monitor changes in cognitive function and adjust treatment as necessary.
Non-amyloid drugs
Medications address different pathways involved in cognitive decline, they help to:
- Improve Cognitive Function: By enhancing cholinergic transmission or regulating glutamate activity, these drugs can improve memory, attention, and overall cognitive function.
- Delay Symptom Progression: Although not a cure, these medications can slow the worsening of symptoms, providing patients and caregivers with more quality time.
- Enhance Quality of Life: By maintaining cognitive and functional abilities longer, patients can enjoy a better quality of life and more independence.
Aricept (Donepezil)
- Purpose: Treats mild to moderate Alzheimer's.
- Mechanism: Increases acetylcholine.
- Common Side Effects: Nausea, diarrhea, insomnia, muscle cramps, fatigue.
- Precautions: Inform doctor about heart conditions, asthma, or ulcers. Monitor for gastrointestinal bleeding.
Memantine
- Purpose: Treats moderate to severe Alzheimer's.
- Mechanism: Regulates glutamate activity.
- Common Side Effects: Dizziness, headache, constipation, confusion, hypertension.
- Precautions: Inform doctor about kidney problems or seizure history. Monitor kidney function.
Galantamine
- Purpose: Treats mild to moderate Alzheimer's.
- Mechanism: Increases acetylcholine and receptor sensitivity.
- Common Side Effects: Nausea, vomiting, diarrhea, weight loss, dizziness.
- Precautions: Inform doctor about heart problems, liver issues, or gastrointestinal disorders. Monitor for gastrointestinal bleeding.
