Panayiotopoulos syndrome is remarkably benign in terms of its evolution. The risk of developing epilepsy in adult life is probably no more than of the general population. Most patients have one or 2-5 seizures. Only a third of patients may have more than 5 seizures, and these may be frequent, but outcome is again favorable. However, one fifth of patients may develop other types of infrequent, usually rolandic seizures during childhood and early teens. These are also age-related and remit before the age of 16 years. Atypical evolutions with absences and drop attacks are exceptional. Children with pre-existing neurobehavioral disorders tend to be pharmacoresistant and have frequent seizures though these also remit with age.

Formal neuropsychological assessment of children with Panayiotopoulos syndrome showed that these children have normal IQ and they are not on any significant risk of developing cognitive and behavioural aberrations, which when they occur they are usually mild and reversible. Prognosis of cognitive function is good even for patients with atypical evolutions.

However, though Panayiotopoulos syndrome is benign in terms of its evolution, autonomic seizures are potentially life-threatening in the rare context of cardiorespiratory arrest.

The prognosis for Rolandic seizures is invariably excellent, with probably less than 2% risk of developing absence seizures and less often GTCS in adult life.

Remission usually occurs within 2–4 years from onset and before the age of 16 years. The total number of seizures is low, the majority of patients having fewer than 10 seizures; 10–20% have just a single seizure. About 10–20% may have frequent seizures, but these also remit with age.

Children with Rolandic seizures may develop usually mild and reversible linguistic, cognitive and behavioural abnormalities during the active phase of the disease. These may be worse in children with onset of seizures before 8 years of age, high rate of occurrence and multifocal EEG spikes.

The development, social adaptation and occupations of adults with a previous history of Rolandic seizures were found normal.

Panayiotopoulos syndrome probably affects 13% of children aged 3 to 6 years who have had 1 or more afebrile seizures and 6% of such children in the 1- to 15-year age group. All races and both sexes are affected.

Socioeconomic correlates of health have been well established in the study of heart disease, lung cancer, and diabetes. Many of the explanations for the increased incidence of these conditions in people with lower socioeconomic status (SES) suggest they are the result of poor diet, low levels of exercise, dangerous jobs (exposure to toxins etc.) and increased levels of smoking and alcohol intake in socially deprived populations. Hesdorffer et al. found that low SES, indexed by poor education and lack of home ownership, was a risk factor for epilepsy in adults, but not in children in a population study. Low socioeconomic status may have a cumulative effect for the risk of developing epilepsy over a lifetime.

The cause of FIRES is not known. It does not happen twice in the same family, but the medical community does not know if it is genetic. It happens in boys more than girls. After the initial status, life expectancy is not affected directly. Issues such as overdose of medications or infections at a food tube site are examples of things that would be secondary to the status.

The age of onset ranges from 1 to 14 years with 75% starting between 7–10 years. There is a 1.5 male predominance, prevalence is around 15% in children aged 1–15 years with non-febrile seizures and incidence is 10–20/100,000 of children aged 0–15 years

Following a first seizure, the risk of more seizures in the next two years is 40%–50%. The greatest predictors of more seizures are problems either on the electroencephalogram or on imaging of the brain. In adults, after 6 months of being seizure-free after a first seizure, the risk of a subsequent seizure in the next year is less than 20% regardless of treatment. Up to 7% of seizures that present to the emergency department (ER) are in status epilepticus. In those with a status epilepticus, mortality is between 10% and 40%. Those who have a seizure that is provoked (occurring close in time to an acute brain event or toxic exposure) have a low risk of re-occurrence, but have a higher risk of death compared to those with epilepsy.

Jeavons syndrome is a lifelong disorder, even if seizures are well controlled with antiepileptic drugs. Men have a better prognosis than women. There is a tendency for photosensitivity to disappear in middle age, but eyelid myoclonia persists. It is highly resistant to treatment and occurs many times a day, often without apparent absences and even without demonstrable photosensitivity.

There were also observations that hippocampal sclerosis was associated with vascular risk factors. Hippocampal sclerosis cases were more likely than Alzheimer's disease to have had a history of stroke (56% vs. 25%) or hypertension (56% vs. 40%), evidence of small vessel disease (25% vs. 6%), but less likely to have had diabetes mellitus (0% vs. 22%).

The number cases of PRES that occur each year is not known. It may be somewhat more common in females.

Both medication and drug overdoses can result in seizures, as may certain medication and drug withdrawal. Common drugs involved include: antidepressants, antipsychotics, cocaine, insulin, and the local anaesthetic lidocaine. Difficulties with withdrawal seizures commonly occurs after prolonged alcohol or sedative use, a condition known as delirium tremens.

Many cases resolve within 1–2 weeks of controlling blood pressure and eliminating the inciting factor. However some cases may persist with permanent neurologic impairment in the form of visual changes and seizures among others. Though uncommon, death may occur with progressive swelling of the brain (cerebral edema), compression of the brainstem, increased intracranial pressure, or a bleed in the brain (intracerebral hemorrhage). PRES may recur in about 5-10% of cases; this occurs more commonly in cases precipitated by hypertension as opposed to other factors (medications, etc.).

Complex partial status epilepticus (CPSE) is one of the non-convulsive forms of status epilepticus, a rare form of epilepsy defined by its recurrent nature. CPSE is characterized by seizures involving long-lasting stupor, staring and unresponsiveness. Sometimes this is accompanied by motor automatisms, such as eye twitching.

Between 10 and 30% of people who have status epilepticus die within 30 days. The great majority of these people have an underlying brain condition causing their status seizure such as brain tumor, brain infection, brain trauma, or stroke. However, people with diagnosed epilepsy who have a status seizure also have an increased risk of death if their condition is not stabilized quickly, their medication and sleep regimen adapted and adhered to, and stress and other stimulant (seizure trigger) levels controlled.

However, with optimal neurological care, adherence to the medication regimen, and a good prognosis (no other underlying uncontrolled brain or other organic disease), the person—even people who have been diagnosed with epilepsy—in otherwise good health can survive with minimal or no brain damage, and can decrease risk of death and even avoid future seizures.

Febrile infection-related epilepsy syndrome (FIRES) is a form of epilepsy that affects children three to fifteen years old. A healthy child that may have been ill in the last few days or with a lingering fever goes into a state of continuous seizures. The seizures are resistant to seizure medications and treatments, though barbiturates may be administered. Medical diagnostic tests may initially return no clear diagnosis and may not detect any obvious swelling on the brain. The syndrome is very rare: it may only affect 1 in 1,000,000 children.

Status marmoratus is a congenital condition due to maldevelopment of the corpus striatum associated with choreoathetosis, in which the striate nuclei have a marble-like appearance caused by altered myelination in the putamen, caudate, and thalamus(there is bilateral hyperdensities restricted to thalamus ). This causes lesions resulting from acute total asphyxia in the basal nucleus of full-term infants. Associated with athetoid cerebral palsy.

The most potent precipitating factor is eye closure, whether voluntary, involuntary or reflex. Most and, in some patients, all of the seizures are induced immediately after closure of the eyes in the presence of uninterrupted (non-flickering) light. Eye closure in total darkness is ineffective.

Contrary to other forms of photosensitive epilepsies that are sensitive only to flickering lights, patients with Jeavons syndrome are also sensitive to bright, non-flickering lights. This is probably due to the enhancing effect of bright light on the sensitivity of eye closure.

In the United States, about 40 cases of SE occur annually per 100,000 people. This includes about 10–20% of all first seizures.

Treatment is in the form of anti-epileptic drugs, such as barbiturates, benzodiazepines and topiramate.

Status dystonicus is a serious and potentially life-threatening disorder which occurs in people who have primary or secondary dystonia. Symptoms consist of widespread severe muscle contractions. Treatment can be difficult but status dystonicus may respond to midazolam, propofol, baclofen and pallidal deep brain stimulation.

A lack of motivation has been reported in 25–50% of patients with Alzheimer's disease. While depression is also common in patients with this disease, aboulia is not a mere symptom of depressions because more than half of the patients with Alzheimer's disease with aboulia do not suffer from depression. Several studies have shown that aboulia is most prevalent in cases of severe dementia which may result from reduced metabolic activity in the prefrontal regions of the brain. Patients with Alzheimer's disease and aboulia are significantly older than patients with Alzheimer's who do not lack motivation. Going along with that, the prevalence of aboulia increased from 14% in patients with a mild case Alzheimer's disease to 61% in patients with a severe case of Alzheimer's disease, which most likely developed over time as the patient got older.

Many different causes of aboulia have been suggested. While there is some debate about the validity of aboulia as a separate disease, experts mostly agree that aboulia is the result of frontal lesions and not with cerebellar or brainstem lesions. As a result of more and more evidence showing that the mesolimbic and the mesocortical dopamine system are key to motivation and responsiveness to reward, aboulia may be a dopamine-related dysfunction. Aboulia may also result from a variety of brain injuries which cause personality change, such as dementing illnesses, trauma, or intracerebral hemorrhage (stroke), especially stroke causing diffuse injury to the right hemisphere.

Persistent aura without infarction (PAWOI) is a little-known condition, first described under the designation prolonged migraine aura status, that is not yet fully understood. PAWOI is said to be a possible cause of a variety of neurological symptoms, including visual snow, loss of vision, increased afterimages, tinnitus, and others. However, the pathogenesis of PAWOI is unknown; in other words, it is not known exactly what causes these symptoms. Furthermore, it is not clear which medical examinations are useful in diagnosing PAWOI. At present, PAWOI is usually diagnosed solely based on the patient's present and past symptoms. It may be possible that an overactive brain or a chemical imbalance is partly to blame for the disorder.

Different medication has been tried as treatment, notably acetazolamide, valproate, lamotrigine, topiramate, and furosemide.

BFS has been reported in other African cultures, and also in Brazil, Argentina, and Ethiopian Jews. Historic higher reported prevalence among males may be due to more males being present in higher education in African countries. Studies since the 1990s have not verified gender differences. Other studies found a possible association with low socioeconomic status, an association with average or higher intelligence, and a high association with neuroticism. Individuals with BFS have been found to have problems with isolation, poor study habits, and the use of psychostimulants as well as physical changes including in muscle tension and heart rate.

Anumonye reported treatment success with lorazepam; others found benefit with antidepressants and relaxation exercises.
