Parkinson's disease is the second most common neurodegenerative disorder worldwide, affecting millions of people and leading to progressive movement difficulties . Diagnosing Parkinson's disease relies primarily on clinical evaluation, as there is no definitive laboratory or imaging test that can confirm the disease . Early and accurate diagnosis is essential for managing symptoms and improving quality of life .

Alzheimer’s disease affects millions worldwide and often leads to severe cognitive decline and behavioral symptoms that disrupt daily life . Sleep disturbances and mood disorders are common in Alzheimer’s patients, worsening their quality of life and increasing caregiver burden . Emerging research suggests that light therapy, including bright light exposure and photobiomodulation, may help improve these symptoms by regulating circadian rhythms and brain function .

Loneliness affects nearly a quarter of older adults and has been linked to a significantly increased risk of stroke. Recent research shows that individuals experiencing chronic loneliness have a 56% higher chance of suffering a stroke compared to those with low loneliness levels, even after accounting for other risk factors .
