Sleep Spindles Organization as an Early Neural Marker of Neuromotor Outcome (SONNO)

February 5, 2024 updated by: Viviana Marchi, IRCCS Fondazione Stella Maris

SONNO - Sleep Spindles Organization as an Early Neural Marker of Neuromotor Outcome: a New, Fast, Safe, Cost-effective and Infant-friendly EEG Tool to Monitor Early Sensory-motor Function in Infants at Risk of Neuromotor Disorders.

The goal of this observational study is to test the effectiveness of quantitative early biomarkers in the sleep electroencephalogram (EEG), namely sleep spindles, as predictors of early sensorimotor maturation and long-term motor outcome. Spindles are discrete events, prominent over sensorimotor areas, that reflect motor learning overnight consolidation. They represent a potential marker for the investigation of altered early sensorimotor reorganization and long-term motor outcomes in the case of neuromotor pathologies. To test this hypothesis, we will validate the prognostic accuracy of a semi-automated EEG sleep-spindles analysis in two clinical populations: 1) infants with a perinatal brain lesion, at risk of Cerebral Palsy (CP), 2) infants with Spinal muscular atrophy type 1 (SMA1), a neuromuscular disease detectable at birth with variable response to early pharmacological treatment. A group of typically developing infants (at very low neurological risk) will be enrolled in the study as control group. All participants will undergo two sleep EEG recordings at 2-5 months (T1) and 12 months (T2), respectively. Short-term neuromotor outcome will be evaluated at T1 and T2, through standard and validated assessment. Long-term neuromotor development will be defined at 18 months (T3; i.e. CP vs NO CP; SMA treatment responders vs No responders). Primary clinical and motor outcomes will be used for estimating the effectiveness of spindles' features at T1 and T2 as predictors of later clinical and motor outcomes at T3. EEG sleep features will be considered both cross-sectionally, at each time point (T1, and T2), and from a longitudinal perspective. Differences in the EEG sleep-spindle features will be evaluated within- and between-groups.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

  • Infants at risk of Cerebral Palsy
  • Infants with diagnosis of SMA type 1
  • Infants at very low neurodevelopmental risk (control group)

Description

Inclusion Criteria:

  • Infants aged 0-5 months who are at high-risk of Cerebral Palsy (CP): preterm and at term infants with a documented pre- or perinatal brain lesion at the neonatal brain MRI (i.e. hypoxic-ischemic brain injury, ischemic or hemorrhagic stroke, cystic periventricular leukomalacia, periventricular hemorrhagic infarction associated with germinal matrix-intraventricular haemorrhage);
  • Infant aged 0-5 months who have received the diagnosis of SMA1, according to the perinatal genetic screening, and undergo early pharmacological treatment;
  • Infants aged 0-5 months at very low neurodevelopmental risk (Control group): infants born preterm or at term in absence of perinatal neurological complications.

Exclusion Criteria (apply all groups):

  • Presence of drug-resistant epilepsy or active epilepsy at T1,
  • Severe sensory deficits (blindness or deafness)
  • Diagnosis of progressive neurological disorders, other than SMA.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Infants at risk of Cerebral Palsy

Infants with diagnosis of SMA1
N=20, Infants with a diagnosis of SMA type 1.

N=20, Infants born preterm or at term in absence of perinatal neurological complications, therefore a very low neurodevelopmental risk.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Clinical dichotomous outcome
Time Frame: 18 (+/- 3) months
For infants with perinatal brain damage, the primary outcome will be the diagnosis of CP: CP-YES vs CP-NO. For infants with SMA, the primary outcome will be the response to treatment: responders (SMA-R) vs non-responders (SMA-NR).
18 (+/- 3) months
Sleep EEG (T1,T2) - quantitative sleep spindles analysis
Time Frame: 2-5 months, 12 (+/- 1) months
Primary predictive measure of the study
2-5 months, 12 (+/- 1) months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
General Movements Assessment (GMA; T1)
Time Frame: 2-5 months
Short-term motor outcome
2-5 months
