Effectiveness of L-serine supplementation in children with a loss-of-function mutation: Rationale and protocol for single patient (n-of-1) multiple cross-over trials.

Rationale: Loss-of-function (LoF) mutations in result in neurologic abnormalities due to -methyl-D-aspartate receptor (NMDAR) dysfunction. Affected persons present with various symptoms, including intellectual developmental disability (IDD), hypotonia, communication deficits, motor impairment, complex behavior, seizures, sleep disorders and gastrointestinal disturbance. Recently, experiments showed that D-serine mitigates function to GluN2B (mutation)-containing NMDARs.

Using PRPP-Assessment for measuring change in everyday activities by home-based videos: An exploratory case series study in children with multiple disabilities.

Background: Currently, paediatric health care aims to use a child-centred tailor-made approach. In order to design tailored occupational therapy, the implementation of personalised occupation-based measurements that guide and evaluate goal setting and are responsive to change is necessary.

Purpose: Primarily, this study explored the potential of the Perceive, Recall, Plan, and Perform (PRPP) assessment to measure the change in the performance of children with multiple disabilities.
