What this trial measures

  • Changes in Visual Reception Skills on the Mullen Scales of Early Learningup to 4 years

    Changes in the Visual Reception subscale on the Mullen Scales of Early Learning will be assessed every 6 months. Visual reception skills are a measure of visual processing and problem solving. Raw scores will be used as a measure of visual receptions skills with scores ranging from 0 to 50. Higher scores indicate more visual reception skills.

  • Changes in Fine Motor Skills on the Mullen Scales of Early Learningup to 4 years

    Changes in the Fine Motor subscale on the Mullen Scales of Early Learning will be assessed every 6 months. Fine motor skills are a measure of fine motor coordination. Raw scores will be used as a measure of fine motor skills with scores ranging from 0 to 49. Higher scores indicate more fine motor skills.

  • Changes in Receptive Language Skills on the Mullen Scales of Early Learningup to 4 years

    Changes in the Receptive Language subscale on the Mullen Scales of Early Learning will be assessed every 6 months. Receptive language skills are a measure of the understanding of language. Raw scores will be used as a measure of receptive language skills with scores ranging from 0 to 48. Higher scores indicate more receptive language skills.

  • Changes in Expressive Language Skills on the Mullen Scales of Early Learningup to 4 years

    Changes in the Expressive Language subscale on the Mullen Scales of Early Learning will be assessed every 6 months. Expressive language skills are a measure of how an individual communicates. Raw scores will be used as a measure of expressive language skills with scores ranging from 0 to 50. Higher scores indicate more expressive language skills.

  • Motor and Language Changes on the CLN2 disease rating scaleup to 4 years

    Change in motor and language subscales of the CLN2 disease rating scale. Ranges for scores are 0 to 6 with higher scores indicating more abilities in motor and language skill development.
