Έχει πλάκα όταν μαθαίνεις τα ονόματα γνωστών «παθήσεων» (ή, απλώς, ιδιοτροπιών):

misophonia = μισοφωνία

Misophonia, literally “hatred of sound”, is a form of decreased sound tolerance. It is believed to result from abnormally strong connections between the autonomic and limbic systems in the brain, rather than over-activity in the auditory system itself. The term was coined by American neuroscientists Pawel Jastreboff and Margaret Jastreboff.

Unlike hyperacusis, misophonia is specific for certain sounds. Little is known about the anatomical location of the physiological abnormality that causes such symptoms but it is most likely high central nervous system structures.

Symptoms
People who have misophonia are most commonly annoyed, or even enraged, by the sound of other people eating or breathing. Oddly, they are not normally annoyed by sounds that they themselves make. Reactions to these sounds are not limited however to just loud eating noises. People with misophonia find themselves affected by all kinds of noises.

Often, people who have misophonia are also annoyed by other people's repetitive movements, such as leg-tapping, nail-biting and typing.

Sensitivity to these sounds tends to be exacerbated by stress or feeling tired/run down.

Coping methods and treatment
People with misophonia tend to use varying coping methods. Most people will simply avoid the sound and leave the room/area altogether, whereas some will try and block the sound with earplugs, music/listening to music on headphones and in more extreme cases, not socialise for fear of hearing the sounds.

Although misophonia is quite a common condition, it is not a well-known diagnosis and few treatment options are available. Anxiolytics have been prescribed to help patients feel calmer in situations that would normally cause anger. Some therapists offer sound sensitivity training. They expose a patient to both 'pleasant' and aggravating sounds in the hope that doing so will reduce the immediate feelings of anxiety or rage, and eventually desensitise the person to the offending sounds.


phonophobia = φωνοφοβία

Phonophobia (also called ligyrophobia) is a fear of loud sounds. It can also mean a fear of voices, or a fear of one's own voice. It may also be related to, caused by, or confused with "hyperacusis", extreme sensitivity to loud sounds. Phonophobia also refers to an extreme form of misophonia.


hyperacousis = υπερακουσία

Hyperacusis (also spelled hyperacousis) is a health condition characterized by an over-sensitivity to certain frequency ranges of sound (a collapsed tolerance to normal environmental sound). A person with severe hyperacusis has difficulty tolerating everyday sounds, some of which may seem unpleasantly loud to that person but not to others.
