  Paroxysmal Hemicrania Information Page: National Institute of Neurological Disorders and Stroke (NINDS)
Paroxysmal hemicrania is a rare form of headache that usually begins in adulthood.
Attacks of paroxysmal hemicrania typically occur from 5 to 40 times per day and last 2 to 45 minutes.
Patients with both paroxysmal hemicrania and trigeminal neuralgia (a condition of the 5th cranial nerve that causes sudden, severe pain typically felt on one side of the jaw or cheek) should receive treatment for each disorder.

  Paroxysmal attacks - Wikipedia, the free encyclopedia
Paroxysmal attacks in various disorders have been reported extensively and ephaptic transmission of demyelinated nerves has been presumed as one of the underlying mechanisms of this phenomenon.
Mostly reported paroxysmal attacks are painful tonic spasms dysarthria and ataxia, numbness and hemiparesis.
Paroxysmal attacks of asthma and their prevention Asthma as paroxysmal neurogenic inflammatory disease.

 WE MOVE - Overview of Dyskinesias (Paroxysmal)
Paroxysmal dyskinesias are neurologic conditions characterized by sudden episodes of abnormal involuntary movements (hyperkinesias).
Paroxysmal dyskinesias are often classified into paroxysmal kinesigenic dyskinesia (PKD) and paroxysmal non-kinesigenic dyskinesia (PNKD), based upon precipitating factors that precede or trigger the episodes of abnormal, involuntary movement.
In contrast, in those with non-kinesigenic dyskinesia, the attacks may occur spontaneously while at rest or out of a background of normal motor activity, but may be exacerbated by alcohol or caffeine consumption, stress, fatigue, or other factors.

 Paroxysmal Dyskinesias
Attacks may be so severe that they result in sudden falls or significantly interfere with walking, standing, or performing other activities of daily living (ADLs), potentially resulting in severe disability.
Due to a number of factors--including the sudden, unpredictable, transient nature of paroxysmal dyskinesia, its response to anticonvulsant medications, and the premonitory sensations often preceding episodes--some researchers have suggested that paroxysmal dyskinesia may be epileptic in nature.
A diagnosis of paroxysmal kinesigenic, non-kinesigenic, exertion-induced, or hypnogenic dyskinesia is based upon a thorough clinical evaluation including a complete physical and neurologic assessment; evaluation of characteristic symptoms with assessment of episode duration, frequency, and "trigger factors" or precipitants; and a careful patient and family history.

Analysis of stimuli triggering attacks of paroxysmal dystonia induced by exertion -- Meyer et al.
During the attack, the excitability of the corticospinal system supplying the forearm flexor and extensor muscle increased in parallel (coactivation) as it is reflected by the amplitudes of the motor responses elicited simultaneously by single cortex stimuli in both muscle groups (x-y plot).
Paroxysms were not related to the execution of motor programmes as they could be elicited by brief "myoclonic" jerks.

Paroxysmal hypnogenic dyskinesias may be classified as a form of epilepsy, not dystonia.
History and (ideally) video documentation of the attacks are important tools toward diagnosing PD. The work-up for diagnosing paroxysmal dyskinesias may also include an electroencephalogram (a test to measure brain waves), brain imaging (such as MRI or CT scan), blood chemistries, and calcium tests.
Paroxysmal Hypnogenic Dyskinesia (PHD) is characterized by attacks of dystonia, chorea, or ballism during non-REM sleep.

The primary finding associated with paroxysmal dyskinesia is sudden, transient attacks of chorea, athetosis, dystonia, ballismus, or any combination of these abnormal movements involving muscle groups of the arms, legs, trunk, face, and/or neck.
The transient attacks associated with PKD primarily affect muscles of the arms and legs; however, muscles of the face, neck, and/or trunk may also be involved.

 Paroxysmal Hemicrania Information on Healthline
Paroxysmal hemicrania syndromes have two forms: chronic, in which persons experience attacks on a daily basis for a year or more, and episodic, in which the headaches do not occur for months or years.
The main feature of chronic paroxysmal hemicrania is frequent attacks of strictly one-sided severe pain localized in or around the eye or temple regions, lasting from 2–45 minutes in duration, and occurring 2–40 times per day.
Episodic paroxysmal hemicrania involves attacks of severe pain in the eye or temple area that last about one to 30 minutes, with a frequency of three or more events per day, and clear intervals between bouts of attacks that may last from months to years.

This condition may be broadly defined as a transient or permanent monocular visual disturbance accompanying a migraine attack or occurring in an individual with a strong history of migrainous episodes.
While a definite diagnosis of migraine was impossible to prove, the mode of onset, the associated headache, the relatively brief duration of the attack, the family history of migraine, the occurrence of other attacks more typically migrainous, and the absence of all neurologic abnormality between episodes made the diagnosis of migraine most likely.
