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).
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
This condition is known as photosensitive epilepsy and, in some cases, the seizures can be triggered by activities that are harmless to others, such as watching television or playing video games, or by driving or riding during daylight along a road with spaced trees, thereby simulating the "flashing light" effect. Some people can have a seizure ...

[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 ...
Ecstatic seizures may provide insight into the understanding and treatment of neuropsychiatric disorders. [4] [2] The dorsal anterior insula has been proposed as a potential novel therapeutic target for treatment of neuropsychiatric disorders like severe depression, for instance through non-invasive intermittent brain stimulation techniques. [16]
Other precipitants can trigger an epileptic seizure in patients who otherwise would be susceptible to spontaneous seizures. For example, children with childhood absence epilepsy may be susceptible to hyperventilation. In fact, flashing lights and hyperventilation are activating procedures used in clinical EEG to help trigger seizures to aid ...
Seizures usually begin around puberty and usually have a genetic basis. [4] Seizures can be stimulus-selective, with flashing lights being one of the most common triggers. [4] Juvenile myoclonic epilepsy (JME) is a prevalent and typical form of idiopathic generalized epilepsy (IGE) syndrome.
