Morning headache is a pattern, not a diagnosis
Sleep-related and pressure-related causes are different possibilities; headache timing and vision symptoms matter.
Several explanations may be worth exploring
- Sleep-disordered breathingPoor sleep and nocturnal breathing disturbances can contribute to waking headaches.
- Raised intracranial pressureCertain pressure-related conditions need targeted clinical and eye assessment beyond a routine MRI.
- Migraine or primary headacheMigraine can occur at particular times or respond to posture without a structural lesion.
- Medication overuse or medication effectFrequent analgesic use or new medicines may prolong headache cycles.
