Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
NMDA Receptor Antagonist Therapy
Memantine works by regulating glutamate activity to protect nerve cells from excess excitation. It is often combined with cholinesterase inhibitors in moderate-stage disease to provide complementary mechanisms of action.
Combination Therapy
Concurrent use of cholinesterase inhibitors with memantine provides dual-action neurochemical support targeting different neurotransmitter systems. This combination approach may provide greater symptomatic benefits than monotherapy.
Additional treatment options
Behavioral Management Strategies
Non-pharmacological approaches to manage agitation, anxiety, or behavioral changes including environmental modifications, structured routines, and validation therapy techniques. These strategies reduce reliance on psychotropic medications.
psychologicalMIND Diet Protocol
Modified dietary approach specifically developed for brain health that combines Mediterranean diet principles with foods particularly beneficial for cognitive function including leafy greens, berries, and legumes.
