My father was diagnosed with ealry stages of dementia 6 months ago and is on medication to slow the progression. Prior to Christmas, he developed \"noise\" in his head. sometimes he says it is a hissing; other times it is a feeeling of wind blowing in his head. it is very disturbing for him. he is agitated and not sleeping. We have had him to an ENT specialist several times, who says that it is not tinitis nor infection. could it be linked to the dementia?
Hi, Welcome to Chat Doctor forum.  It appears that the hissing is in his head, not in the ears. Tinnitus is felt usually in the ears.  As you describe it appears to be the auditory hallucination, due to the dementia.  I advise you to consult a neurologist for diagnosis and treatment. You may need to have a C.T.scan for diagnosis, and to exclude the tinnitus.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods, to have recovery of the brain tissue, and general health.  Wishing for a quick and complete recovery. Thank you.
