People with musicogenic epilepsy may have seizures triggered not just by musical stimuli but also by the emotional content or memory associated with that melody or rhythm. Seizures can also be triggered when people with the condition think about certain kinds of music without actually hearing the music. In addition, musicogenic epilepsy may occur with sounds that one would not usually associate with music, the sounds of machinery for example. While certain types of music may induce a seizure in a certain person, listening to other kinds of music may prevent or terminate the epileptic activity. Intrinsic stimuli
Intrinsic stimuli are specific actions or activities performed by the person that result in a reflex seizure. Intrinsic stimuli can be divided into two categories, either elementary or elaborate. Elementary intrinsic stimuli are usually simple motor movements while elaborate intrinsic stimuli can include emotions, thoughts, calculations or decision making.Thinking epilepsy is a rare form of reflex epilepsy that is triggered by a specific cognitive task. This can include thinking, calculations, solving problems, abstract reasoning, or making decisions. Thinking epilepsy does not occur in response to reading, writing, or verbal communication. Reading epilepsy is recognized as another distinct kind of reflex epilepsy. Thinking epilepsy usually results in generalized seizures which manifest as bilateral monoclonus, absence seizures, or generalized tonic-clonic seizure that are preceded by myoclonic jerks. Cause
Although reflex seizures are thought to have a genetic component, the exact genes involved are unclear.
As of 2016, some genes of interest include:

Pathophysiology
Epileptic seizures occur due to changes in the brain that result in the lowering of the seizure threshold in a particular individual making that person vulnerable to recurring seizures. These changes can be a result of a structural abnormality, brain lesions, or simply a genetic disposition to seizures. In reflex epilepsy, these changes in the brain result in a small area that is capable of interrupting normal firing patterns and more likely to produce the synchronous firing patterns that characterize a seizure. These hyper-excitable areas may then be activated by certain stimuli resulting in a reflex seizure. Reflex seizures are thus notable because the presentation of a particular stimulus, that activates the hyper-excitable areas of the brain, directly overcomes the seizure threshold, and results in a reflex seizure.The activation of the hyper-excitable areas of the brain are additionally regulated by facilitating factors that may increase the likelihood of eliciting a seizure. Most commonly these include fatigue, sleep deprivation, or stress. Facilitating factors are different for each individual. Due to the large variance between the different kinds of reflex epilepsies, the specific mechanism causing reflex seizures may vary. Diagnosis
The diagnosis of reflex epilepsy usually includes a comprehensive medical and family history as well as a variety of tests. These tests may include a electroencephalography (EEG), magnetic resonance imaging (MRI), as well as genetic testing.The procedure for diagnosing epilepsy generally follows three steps:
Determining if the seizure or seizure like event is truly an epileptic seizure.
