The diagnosis of infantile spasms mainly relies on EEG recordings, combined with growth and development assessments and neuroimaging examinations.

Infantile spasms, also known as West Syndrome or the opisthotonic syndrome, can lead to sequelae as they grow up, but proper treatment can stabilize the condition.

Infantile spasms, also known as West syndrome, is a rare disease. The disease usually begins in children between 4 to 6 months after birth. The convulsions are characterized by sudden, repetitive flexion or extension movements, and the symptoms usually disappear by the age of 2 to 4 years. The medication commonly used for infantile spasms is not very effective, and most children may suffer from serious residual symptoms.
