A report from Amar Desh Online on June 30, 2026, highlighted multiple factors that can lead to reduced memory and cognitive performance. The article noted that fatigue, stress, heavy workloads, post-COVID effects, lack of sleep, poor nutrition, and thyroid disorders may temporarily impair brain function. Experts observed that such issues are increasingly common among young professionals.

Nutritionists identified dehydration as a major cause of declining memory and focus. Insufficient water intake can disrupt brain function, slow neural communication, and increase fatigue, making it harder to think or remember information. Prolonged dehydration may also contribute to premature aging and chronic health risks. Other causes include aging, sleep deprivation, vitamin B12 deficiency, head injuries, side effects of certain medications, neurological diseases such as Alzheimer’s and Parkinson’s, and brain infections or strokes.

The report advised maintaining brain health through adequate hydration, balanced nutrition, regular sleep, stress management, and physical exercise. Persistent or worsening memory problems should be evaluated by a physician.
