[|Human|] i have an extremely loud ticking noise in my head at all times. it sounds like a grandfather clock sort of and it has been in my head for as long as i could remember. as a kid i thought it was normal, until i mentioned it to my friend who thought i was crazy. a friend of mine was recently diagnosed with brain cancer and i began to worry for my own health. what is this ticking noise?
[|AI|]  Hi, Your symptoms are not consistent with any serious organic disease of brain. Ticking sound usually occurs in ear disease, where ticking occurs at ear. Rarely small cysts in brain like arachnoid cyst, pineal cyst produce ticking sound secondary to arterial impulse conduction along the cyst. Stress is another cause for feeling of ticking in headcount neurologist for neurological examination. Ct scan brain to be done to rule out structural lesion. Hope this will help regards Chat Doctor.
