A 2025 study suggests that very low levels of lithium in the brain might be linked to Alzheimer's disease. In mice, certain lithium supplements seemed to protect memory and the brain. But scientists don't yet know if lithium pills are safe or helpful for people.

Cervical dystonia is a movement disorder that causes involuntary, sustained muscle contractions that make the head wobble or rest in abnormal positions. Symptoms can be disruptive, making it hard for people with the condition to drive, dress, or reach for objects.

A sinus headache usually stems from irritated, congested sinuses that create pressure and pain around the eyes, nose, or forehead. Relief often comes from easing inflammation and congestion with a mix of home measures and over-the-counter treatments.

Daily nasal irrigation (nasal rinses) may reduce symptom severity and the duration of a cold. It can also relieve the congestion caused by sinus infections and allergies. By means of a squeeze bottle, neti pot, or battery-powered system, saline is inserted into one nostril and flows out the other.
