Summary

Alzheimer's disease (AD) research increasingly addresses behavioral symptoms (BPSSD), not just cognitive decline. Understanding neuroanatomy and neurotransmitters is key for effective AD and BPSSD treatments.

Background:

Alzheimer's disease (AD) research historically prioritized cognitive deficits.
AD frequently presents with complex affective and behavioral disorders, termed Behavioral and Psychological Signs and Symptoms of Dementia (BPSSD).
BPSSD significantly impair daily functioning and burden caregivers.

Purpose of the Study:

To highlight the importance of addressing BPSSD in Alzheimer's disease research.
To emphasize the need for reliable assessment and diagnostic tools for BPSSD.
To underscore the necessity of understanding the neurobiological underpinnings of BPSSD.

Main Methods:

Reviewing current research on Alzheimer's disease and associated behavioral symptoms.
Examining the link between neuroanatomical/neurochemical dysfunction and behavioral disorders in AD.
Considering the development of assessment and diagnostic tools for BPSSD.

Main Results:

BPSSD are a critical, yet often under-addressed, component of Alzheimer's disease.
Understanding the cortical-subcortical network dysfunction is crucial for explaining BPSSD.
Current therapeutic approaches for AD may not adequately address the specific needs related to BPSSD.

Conclusions:

Future Alzheimer's disease research must integrate the study of BPSSD.
Neuroanatomical and neurochemical insights are vital for understanding and treating BPSSD.
Therapeutic strategies for AD should be tailored to address behavioral symptoms, considering specific neurotransmitter systems.
