Infantile spasm is a type of seizure disorder that often occurs in infants between the ages of 3-12 months. The word is spelled as /ˈɪnfəntaɪl spæzəm/ in IPA phonetic transcription. The first syllable, "in", is pronounced with the short "i" sound as in "sit". The second syllable, "fan", is pronounced with the long "a" sound as in "fate". The final syllable, "tile", is pronounced with the long "i" sound as in "tile". The word "spasm" is pronounced as spelled.
Infantile spasms, also known as West syndrome, is a rare type of epilepsy that typically affects infants between the ages of 3 and 12 months. It is characterized by sudden, brief, and involuntary muscle contractions that appear as spasms. These spasms often involve both sides of the body simultaneously, causing a jerking or stiffening of the arms, legs, or trunk. They can occur in clusters, sometimes hundreds of times throughout the day, particularly upon awakening or during sleep.
The exact cause of infantile spasms is not fully understood, but it is believed to be associated with abnormal brain development. It can be a symptom of an underlying neurological condition, such as tuberous sclerosis, Down syndrome, or brain malformations. However, in many cases, the cause remains unknown.
Diagnosis of infantile spasms typically involves a detailed medical history, physical examination, and electroencephalogram (EEG) to measure brain activity. The spasms often have a characteristic pattern on the EEG, which aids in diagnosis.
Immediate treatment for infantile spasms is crucial, as delays can lead to developmental delays and cognitive impairments. The most common treatment approach is the use of anti-seizure medications, such as corticosteroids or adrenocorticotropic hormone (ACTH), to control and reduce the frequency of the spasms. In some cases, other medications or surgical interventions may be required.
Long-term outcomes for individuals with infantile spasms vary. Some children may outgrow the spasms and have normal development, while others may experience ongoing seizures or developmental delays. Early intervention, supportive therapies, and ongoing medical management are essential for optimizing outcomes in infants with this condition.
The word "infantile" is derived from the Latin word "infans", which means "baby" or "young child". It is combined with the suffix "-ile", which is used to form adjectives indicating a characteristic or a condition.
The term "spasm" comes from the Greek word "spasmos", meaning "convulsion" or "contraction".
So, "infantile spasm" refers to a type of seizure disorder characterized by sudden, brief episodes of spasms or jerking movements in infants or young children.
