While an EEG typically tests varied frequencies of a light stimulus, musicogenic seizures are stimulated differently by music. [11] Moreover, there may be a time period delay between the music or sound stimulus received and seizure triggered. [11] The time gap between the stimulus and the response heightens the challenge of diagnoses.
Musicogenic epilepsy is a form of reflex epilepsy with seizures elicited by special stimuli. [ 1 ] [ 2 ] It has probably been described for the first time in 1605 by the French philosopher and scholar Joseph Justus Scaliger (1540-1609). [ 3 ]
[2] [7] [3] [8] Some of the more common types of reflex epilepsy include light and music. [3] Photosensitive epilepsy is an abnormal sensitivity of the brain to visual stimuli and is the most common trigger in reflex seizures. [3] Reflex seizures can be induced by both flickering or non-flicking light, television, video games, or other visual ...
In summary, musical hallucinations can be separated into five categories according to their cause: hypoacusis, psychiatric disorders, brain lesions, epilepsy, and substance use. However, certain factors can trigger hallucinations, these factors include, old age, social isolation and even gender. [15]
Photosensitive epilepsy (PSE) is a form of epilepsy in which seizures are triggered by visual stimuli that form patterns in time or space, such as flashing lights, bold, regular patterns, or regular moving patterns. PSE affects approximately one in 4,000 people (5% of those with epilepsy).
Researcher Vicky Williamson at Goldsmiths, University of London, found in an uncontrolled study that earworms correlated with music exposure, but could also be triggered by experiences that trigger the memory of a song (involuntary memory) such as seeing a word that reminds one of the song, hearing a few notes from the song, or feeling an emotion one associates with the song.
Sleep deprivation is the second most common trigger of seizures. [15] In some cases, it has been responsible for the only seizure a person ever has. [41] However, the reason for which sleep deprivation can trigger a seizure is unknown. One possible thought is that the amount of sleep one gets affects the amount of electrical activity in one's ...
Episodes of vasovagal syncope are typically recurrent and usually occur when the predisposed person is exposed to a specific trigger. Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
