Sleep Profile of Patients With Septo-optic Dysplasia

IRCCS National Neurological Institute "C. Mondino" Foundation

Status: Enrolling

Conditions: Agenesis of Corpus Callosum; Septo-Optic Dysplasia; Blindness

Treatments: Diagnostic Test: Actigraphy, blood and salivary sample, and sleep evaluation

Study type: Observational

Funder types: Other

Identifiers

NCT06262152

Details and patient eligibility

About

The aim of this study is to evaluate sleep of patients with septo-optic dysplasia compared to patients with an isolated disorder of peripheral visual system and patients with corpus callosum agenesis since both visus defict and agenesis of corpus callosum might be present SOD but associated to other features / structural and functional anomalies.

Included patients and their caregivers will be asked to compile standardize sleep questionnaires and a sleep screening through an interview will be scheduled. Patients will be asked to wear an actigraph on their non-dominant hand wrist for 7 days.

Full description

The primary objective of this study is to evaluate sleep of patients with septo-optic dysplasia compared to patients with an isolated disorder of peripheral visual system and patients with corpus callosum agenesis since both visus defict and agenesis of corpus callosum might be present SOD but associated to other features / structural and functional anomalies.

The secondary aims of this study are the following:

1. identify which factors such as clinical and neuroanatomical features including sensory experience influence sleep outcome and how
2. describe melatonin profile of patients with SOD
3. describe sleep EEG of patients with SOD

Three groups of patients will be included:

• Group A: patients with septo-optic dysplasia
• Group B: patients with disorder of peripheral visual system
• Group C: patients with Corpus Callosum agenesis

This is an observational monocentric study. The procedures in the study that are not included in current clinical practice in the follow-up pathway of the included patients are the following:

• administration of standardized sleep questionnaires (Pittsburgh Sleep Quality Index: self-completed questionnaire assessing sleep quality over a 1-month time interval;Epworth Sleepiness Scale: self-completed questionnaire assessing daytime sleepiness; Children sleep habits questionnaire)
• 7 days actigraph recording through wearing of Actiwatch spectrum plus at home
• Performance of Sleep EEG
• Performance of blood and salivary sampling for melatonin dosing (for each subject, one 4 mL blood and one 2 mL saliva samples will be collected at each assessment)

Enrollment: 45 estimated patients

Sex: All

Ages: 3 to 18 years old

Volunteers: No Healthy Volunteers
