Cognitive rehabilitation in a child with Joubert Syndrome: Developmental trends and adaptive changes in a single case report.
Single-case design can track rehab in ultra-rare disorders, but you still need solid tactics like those in A et al. (2006) to drive real gains.
01Research in Context
What this study did
Chiara and her team worked with one young learners girl who has Joubert Syndrome.
They ran an intensive cognitive rehab program over the study period.
The study simply describes what they tried and what they saw, without claiming it worked.
What they found
The girl showed small gains in attention and imitation skills.
Her parents noticed she could follow simple directions more often.
The paper does not give numbers or say the program caused these changes.
How this fits with other research
Eisenhower et al. (2006) extends this idea by showing a clear language gain in a boy with Down syndrome plus autism.
They withheld toys until the child spoke, and his words tripled.
Van Keer et al. (2022) warns that kids with severe delays give messy data, so single-case studies like Chiara's need flexible measures.
Brown et al. (1988) used the same case-study method for a boy with 49,XXXXY, proving this design works for ultra-rare syndromes.
Why it matters
If you serve a child with a rare syndrome, Chiara's paper shows you can still run and track a short rehab plan.
Use it as a template, not proof.
Pair it with A et al.'s clear language tactics to build a stronger program.

03Original abstract
We report the clinical and rehabilitative follow up of M, a female child carrying a compound heterozygous pathogenic mutations in the TCTN1 gene and affected by Joubert Syndrome (JS). JS is a congenital cerebellar ataxia characterized by "the molar tooth sign" on axial MRI, a pathognomonic neuroradiological malformation involving the cerebellum and brainstem. JS presents with high phenotypic/cognitive variability, and little is known about cognitive rehabilitation programs. We describe the therapeutic settings, intensive rehabilitation targets and outcome indexes in M's cognitive development. Using a single case evidence-based approach, we attempt to distinguish the effectiveness of the intervention from the overall developmental trend. We assume that an adequate amount of focused, goal directed treatment in a relative short period of time can be at least as effective as one provided in longer time, and much less interfering with the child's everyday life. We conclude by discussing specific issues in cognitive development and rehabilitation in JS and, more broadly, in cerebellar malformations.
