Hemiplegic migraine
Hemiplegic Migraine
Hemiplegic Migraine (pronunciation: hem-i-plej-ik mi-grain) is a rare and severe subtype of migraine characterized by temporary paralysis or neurological deficits prior to or during the headache.
Etymology
The term "Hemiplegic Migraine" is derived from the Greek words 'hemi' meaning 'half', and 'plegia' meaning 'paralysis'. The term 'migraine' is derived from the Greek word 'hemicrania', meaning 'half of the skull', referring to the unilateral nature of the headache.
Definition
Hemiplegic Migraine is a type of migraine with aura where the aura includes motor weakness. In some cases, it can also involve vision changes, difficulty speaking, and other sensory disturbances. These symptoms typically precede the headache phase of the migraine, but they may also occur during the headache phase.
Symptoms
The symptoms of Hemiplegic Migraine often begin with an aura that can include vision changes, difficulty speaking, and tingling or numbness. This is followed by temporary paralysis or weakness on one side of the body (hemiplegia), which can last from a few hours to several days. The headache phase of the migraine typically follows the aura and can be severe.
Causes
Hemiplegic Migraine is often associated with genetic mutations, and it can run in families. This type of migraine is often referred to as Familial Hemiplegic Migraine (FHM) when it occurs in two or more family members. There are also cases of Sporadic Hemiplegic Migraine (SHM), where there is no family history of the condition.
Treatment
Treatment for Hemiplegic Migraine typically involves managing symptoms and preventing future attacks. This can include medications to treat acute attacks, preventive medications, and lifestyle changes to avoid migraine triggers.
