Early Infantile Krabbe Disease (EIKD)
Onset of symptoms: 0 – 12 months
Early Infantile Krabbe Disease (EIKD) is the most severe form affecting ~85-90% of all cases.1 As with many lysosomal storage disorders, babies may appear normal for the first few months of life and then begin to develop noticeable symptoms. Infantile Krabbe disease is the most common and most severe form of Krabbe. The onset of symptoms of the Infantile form appears clinically between 0-13 months of age. Learn more about diagnosis, treatment and care of EIKD.
Some of the key characteristics associated with Infantile Krabbe disease are:
- Extreme irritability; above and beyond colic
- Sensitivity to sound; easily startles

Late Infantile Krabbe Disease (LIKD)
Onset of symptoms: 13 – 36 months
Symptoms of the Late Infantile Krabbe Disease (LIKD) usually present between 13 and 36 months of age. Some early symptoms may present with vision disturbances, slurred speech, abnormal gait and loss of previously achieved milestones. Some patients may be diagnosed with this form through a state Newborn Screening Program. These patients will be monitored closely by Krabbe disease experts as to when treatments options should occur.

Juvenile Onset Krabbe Disease (JOKD)
Onset of symptoms: 4 – 18 years
In a relatively small number of patients, Krabbe disease does not appear until later in childhood or adolescence (between 4 to 18 years of age). The onset of symptoms can present quickly or slowly over time. There is also a variable rate at which the disorder progresses. Learn more about diagnosis, treatment and care of JOKD.
