Prognostic role of Mini-Mental State Pediatric Examination (MMSPE) on neuropsychological functioning.

OBJECTIVE: The aim of this study was to evaluate the ability of the Mini-Mental State Pediatric Examinations (MMSPE) in the individuation of neuropsychological impairments. METHOD: MMSPE was administered to 60 children attending a primary or lower secondary school suffering from neurological diseases, admitted to our neuropsychology services. All children performed both a MMSPE examination and a neuropsychological evaluation. Results of neuropsychological evaluation and MMSPE were dichotomized. Positive predictive value (PPV), negative predictive value (NPV), and accuracy were also calculated. RESULTS: The diagnostic performance of MMSPE showed a good overall accuracy (0.83, CI 95% 0.64-0.91), NPV (0.81, CI 95% 0.73-1.00), PPV (0.87, CI 95% 0.68-0.94), specificity (0.91, CI 95% 0.81-1.00), sensitivity (0.74, CI 95% 0.57-0.90), and odds ratio of 28.5 (CI 95% 6.6-123), p < 0.001. CONCLUSIONS: MMSPE has a good prognostic ability in predicting neuropsychological problems in the context of different neurological pediatric diseases. We suggest that this instrument could greatly improve pediatric clinical practice in identifying high-risk children.

Tuberous sclerosis-associated neuropsychiatric disorders: a paediatric cohort study.

AIM: We aimed to study tuberous sclerosis-associated neuropsychiatric disorders (TAND) in children and adolescents with tuberous sclerosis complex (TSC). METHOD: Retrospective and prospective cohort study conducted at a Paediatric Neurology Unit of an Italian Tertiary Care Hospital. Clinical and neuroimaging data were reviewed. Scores for neurological and epilepsy outcomes (Extended Glasgow Outcome Scale, Paediatric Version and Early Childhood Epilepsy Severity Scale modified), semi-structured interviews (authorized Italian version of the TAND checklist and Vineland Adaptive Behavior Scales) and questionnaires (Child Behavior Checklist [CBCL]) were applied at last follow-up. RESULTS: Thirty-two patients with TSC (age range 1-19y) were enrolled. Eighty-eight per cent had at least one TAND and 47% had intellectual disability. The TAND checklist showed internalizing problems in 25.8% of cases (vs 41.9% by CBCL), and externalizing problems in 41.9% (vs 9.7% by CBCL). TAND prevailed in patients with de novo mutation of TSC2, high tuber load, and severe neurological and epilepsy outcomes. INTERPRETATION: In our cohort, 78% of patients had more than four TAND behavioural problems; nevertheless, they did not show a constant and specific neuropsychiatric profile. Clinical, neurophysiological, and neuroradiological features were associated with several TAND. The TAND checklist appeared more effective than the CBCL, particularly in detecting externalizing problems. WHAT THIS PAPER ADDS: The Tuberous sclerosis-associated neuropsychiatric disorders (TAND) checklist is an effective tool for TAND screening. The TAND checklist helps define psychopathological and neuropsychiatric aspects in paediatric patients with Tuberous sclerosis complex (TSC). TAND were found in 88% of patients with TSC, whilst 78% had more than four TAND. TAND distribution depends on different clinical and neuroradiological features.

Language abilities and gestural communication in a girl with bilateral perisylvian syndrome: a clinical and rehabilitative follow-up.

We present the neuropsychological and linguistic follow-up of a girl with bilateral perisylvian polymicrogyria during 4 years of gestural and verbal speech therapy. Some researchers have suggested that children with bilateral perisylvian polymicrogyria mentally fail to reach the syntactic phase and do not acquire a productive morphology. This patient achieved a mean length of utterance in signs/gestures of 3.4, a syntactic phase of completion of the nuclear sentence and the use of morphological modifications. We discuss the link between gesture and language and formulate hypotheses on the role of gestural input on the reorganization of compensatory synaptic circuits.
