Summary
This paper reviews how neural pathways, including those involving intrinsically photosensitive retinal ganglion cells (ipRGCs) and the suprachiasmatic nucleus, are altered in Alzheimer's disease. Understanding these disruptions has implications for designing light-based interventions to support circadian entrainment and reduce symptoms such as sundowning in dementia patients.
Key Findings
- ipRGCs relay light information to the SCN (circadian regulation), vLGN, and olivary pretectal nucleus (pupillary light reflex), all of which may be compromised in Alzheimer's disease
- Neural pathway degeneration in Alzheimer's disease implicates circadian rhythm disruption as a key feature of the condition, suggesting light therapy as a potential therapeutic avenue
