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. [ 2 ] [ 7 ] Elementary intrinsic stimuli are usually simple motor movements while elaborate intrinsic stimuli can include emotions, thoughts ...
Reflex syncope can occur in otherwise healthy individuals, and has many possible causes, often trivial ones such as prolonged standing with the legs locked. [ citation needed ] The main danger of vasovagal syncope (or dizzy spells from vertigo) is the risk of injury by falling while unconscious.
Pain, especially from emotion (surprise, fear, annoyance, frustration, and excitement), crying, and fever were provocative factors. Fever was reported as a provocative factor in 14% of cases. Some cases of fever-induced reflex anoxic seizures are likely to be misdiagnosed as febrile (epileptic) seizures, as has been emphasized by a number of ...
Signs and symptoms of neuropathic pain include allodynia (pain caused by non-painful stimuli), hyperalgesia (an increase in pain perception due to painful stimuli), and paresthesia (abnormal sensations such as needle bites, tingling, itching, and decreased or loss of sensitivity).

Complex regional pain syndrome (CRPS type 1 and type 2), sometimes referred to by the hyponyms reflex sympathetic dystrophy (RSD) or reflex neurovascular dystrophy (RND), is a rare and severe form of neuroinflammatory and dysautonomic disorder causing chronic pain, neurovascular, and neuropathic symptoms.
About 6% of those with epilepsy have seizures that are often triggered by specific events, known as reflex seizures. [15] A number of epilepsy syndromes, known as reflex epilepsies, have seizures that are only triggered by specific stimuli. [16] Common triggers include: flashing lights and sudden noises. [15]
The substance can cause side effects in the nervous system, heart and stomach, with some effects mimicking opioid toxicity and withdrawal, according to the Centers for Disease Control and Prevention.
Certain types of seizures are associated with the somatosensory system. Cortical injury may lead to loss of thermal sensation or the ability to discriminate pain. An aura involving thermal and painful sensations is a phenomenon known to precede the onset of an epileptic seizure or focal seizure.
