Musical Ear Syndrome | Musical Tinnitus | Musical Hallucinations

hello humans welcome back to dr rose
helps you here i'm Stephani Rose and i'm an
Audiologist. today we're going to be discussing
Musical Ear Syndrome.
Musical πŸ‘‚ Syndrome is also known as Musical Tinnitus
or Musical Hallucinations. Sometimes people also refer to it as an Auditory
Hallucination but it's usually of the non-psychiatric kind.
So what is it? Well, Musical Ear Syndrome or muisical Tinnitus,
whatever you want to call it, is basically the perception of
music when there's no external music playing. So you have this
experience of hearing the music like it's actually in the room
not just remembering what a song sounds like. What we do know
is that we can classify it as a disorder of the processing of
complex sounds. I've studied several scientific articles for you to bring you
some more information about this subject so i'll put links to those in the
description if you want to take a look at them for yourself.

A review study
in 2009 by copedale titled is Musical Hallucination: an autological phenomenon.
It was actually a review of several research articles
and what they found is that the association reported is
definitely with hearing loss predominantly female
usually over the age of 60 years old but not necessarily those are not
necessarily risk factors for having mes they found that
underlying causes can be neurovascular pathways
that have pathology or psychiatric disorders
or opioid medications but these are not these are mostly
absent in the majority of the cases the otologic system does play a role and
hearing loss may act as the initiating factor
so we see hearing loss a lot in patients who have the musical ear syndrome
and the primary dysfunction they found between all these research articles is
in the auditory association cortex and we'll get into more
specific points with a later study that looked at fMRI
images of people who were actively having musical ear syndrome
or musical tinnitus the first line of treatment
after excluding any other serious factors would be
you know explaining to the patient what it is
and then also to optimize the hearing i have experienced in my career
at least one maybe two patients that had this
one of them was very affected by it and it bothered her a lot
the other one seemed to be able to cope with it more in both of these cases
unfortunately aiding the hearing loss did not really
help as much as they had wanted it to it was still definitely there
even when hearing even when wearing the hearing aids
another patient that i had fit said that it was slightly reduced but definitely
still prominent another interesting study i found for you was
musical ear syndrome in adult cochlear implant patients
there was only one study in this patient population up to this date
and this one was in 2013 by low at all at cambridge university
there were 82 patients in this study and they found
they were all over 18 the age of 18 and those who received cochlear
implants 22 of them had musical ear syndrome
now keep in mind you know seven out of those 82 patients
had the musical ear syndrome before the the surgery
or before getting a cochlear implant but 11 out of the 82 had it
after so they noted that this did affect their emotional state but
most coped pretty well it said so Musical πŸ‘‚ Syndrome can occur prior
to and after cochlear implantation there's
another study i found out of the department of neurology in
Istanbul Turkey at Matape University i'm sorry if
i said that wrong Matape University School of Medicine in
2014.

This one found that you have to be
careful when patients are exhibiting this in
advanced age because that can be very confused with Dementia
so um there has to be careful testing done to rule out if it's one or the
other they found that Musical Ear Syndrome is
suggested to be a variant of Charles Bonnet
Syndrome this is when people who have visual impairments or blindness
have visual hallucinations and can actually have
you know a misfire in the visual cortex so that's kind of interesting and
it kind of makes sense to me when i found that fact
it does say that it's uh frequently seen but rarely diagnosed
and that even though we don't know the mechanism that's caused by this
it's definitely a hypersensitivity in the auditory cortex
they also associated it with sensory deprivation so usually
there is a correlation with hearing loss why we're getting this kind of misfire
in the auditory cortex and they reported that people said that
it sounds it can sound like popular music or orchestral music
sometimes radio tunes so you can have actual
singing along with this not just instrumental music
and it really does sound like it's in the sound field so in
in the room with you um sometimes it can sound like it's coming from another room
i had a lady who uh lived next to like a high school and she
could have sweared that the band was practicing at like 3 a.m and made
several complaints so it was a very real uh sound to her
so that's that one last one i have for you is spontaneous
musical auditory perceptions in patients who have abrupt
bilateral sensory neural hearing loss so this is the one that did the fmri study
of the brain while people were having the musical ear
syndrome and they found that the area of focus where it's happening
is area 39 of broadmen which is the locus for auditory memory
they said that stored musical memory can be released
and a person has musical perceptions without an external source
it's likely that the abrupt loss of the hearing or inner ear function might in
uninhibit so that means not stop uh neuronal groups for storing
auditory memory so something goes wrong and for whatever reason the brain just
releases all this auditory memory you start hearing all
this music for the most part this is completely
benign it doesn't necessarily mean it's an indicator for
something that's a terrible disease so you know i think that maybe cognitive
behavioral therapy or CBT might be useful in this along with
treating the hearing loss so um i will go ahead and post these uh
different interesting articles for you guys
i hope you have a great rest of your week thank you so much for watching
subscribe if you like my videos and i'll see you next week some people call me an audiologist
others call me a hearing nerd being human with hearing loss is like my
superpower as a hearing doctor i get to help people
hear their best while learning about the mysteries of hearing
