Headache disorders are a group of conditions characterized by recurrent pain in the head or neck. The most common types include tension-type headaches, migraines, and cluster headaches. These disorders can vary in intensity, duration, and frequency, affecting daily activities and overall quality of life. The exact causes of headache disorders are often unclear, but they can be triggered by factors such as stress, certain foods, hormonal changes, and environmental conditions. Treatment options may include over-the-counter medications, lifestyle changes, and in some cases, prescription drugs or therapies to manage symptoms and reduce frequency.
