Brief Summary:
This study is a longitudinal and prospective study of the natural history of infantile neuroaxonal dystrophy (INAD).

Condition or disease
Neuroaxonal Dystrophy, Infantile

Detailed Description:

After obtaining informed consent, the study participants' relevant medical records will be collected and reviewed for this study. Next, a clinic visit will be scheduled with the patient's family and an observing MD/DO/MBBS from a sponsor site to confirm and clarify information in the medical records.

A baseline evaluation of clinical status will also be performed during this visit to serve as visit one in this longitudinal, prospective natural history study. Subsequent visits will take place every 6 months, for up to 24 months. Key components of this prospective study at each visit include a neurodevelopment exam tailored for INAD, application of the CHOP-INTEND neurodevelopment scale, the Hammersmith infant neurological examination and the modified Ashworth spasticity scale as well as collection of monthly parental severity scoring and monthly home videos of activities of daily living (ADLs).

Data from this study will be pooled and presented in aggregate, without identification of individual subjects.
