The purpose of this protocol is to allow for the careful evaluation of healthy volunteers and individuals with risk for psychiatric disorders or neurodevelopmental disorders, such as autism spectrum disorder for specific protocols at NIH.
NCT00060541
Objective: This protocol is designed to allow evaluation of participants neurosurgical disorders that receive care within the Surgical Neurology Branch. The participants will receive standard-of-clinical-care evaluation and treatment. The clinical data and samples generated during standard of care treatment will be collected as a part of this study. Study Population: Participants 4 years of age and older with neurosurgical-related conditions seeking care from, or referred to the Surgical Neurology Branch for evaluation are eligible for this protocol. Study Design: This is an observational study. Participants will receive standard-of- clinical-care evaluation and treatment for their neurosurgical condition. Clinical evaluation may include laboratory and radiological studies designed to aid in diagnosis or differential diagnosis of the participant s condition or to facilitate treatment. The evaluations may take place in the outpatient clinic areas or in the inpatient units. Some participants will receive standard-of-care medical or surgical treatment for their disorder. Clinical data, tissue samples or body fluids obtained during standard of care treatment, may be used for research. Additional genetic testing may be performed on subjects and their blood relatives if a genetic mechanism underlying the neurological disorder is suspected. Patients in this study may choose to consent to skin biopsies for research purposes, in which case they will sign an additional consent document for thesethis research procedure. Outcome Measures: No additional research outcome measures will be tracked in this study, as this study is collecting data for potential future use. All outcomes will be those of standard clinical evaluation and treatment. A clinical and research database will be kept of patient s diagnosis, progression, and treatment. Clinical database information may be reported or be used in other studies.

Neuropsychiatric disorders are extremely common, severe, and disabling conditions. In the field of psychiatry, they notably include schizophrenia, mood disorders (depressive and bipolar disorders), autism spectrum or neurodevelopmental disorders, obsessive-compulsive disorder, eating disorders, and personality disorders. In the field of neurology, one can cite neurodegenerative diseases (such as Alzheimer's disease, but also frontotemporal dementia or Parkinson's disease, which often represent frequent and challenging differential diagnoses of psychiatric disorders), focal neurological lesions (notably strokes and tumors), or epilepsy. Cognitive impairments are present in nearly all neuropsychiatric disorders and contribute significantly to disability. While impairments in working memory and attention, executive functions, and social cognition have been relatively well studied, other cognitive domains remain largely unexplored in these populations. This is particularly the case for various aspects of motivation, metacognition, conscious access, or causal (Bayesian) inference. Although these domains likely play an important role in prognosis, no consensus currently exists regarding the methods for evaluating these functions. The main objective of this study is to define a multidimensional, transdiagnostic atlas of high-level cognitive impairments-both specific and shared-across severe psychiatric disorders (notably schizophrenia, depressive disorder, bipolar disorder, autism spectrum or neurodevelopmental disorders, and obsessive-compulsive disorder) and neurological disorders (notably neurodegenerative diseases, focal neurological lesions, and epilepsy), by comparing them to healthy volunteers. The investigators also aim to investigate the progression of cognitive impairments over time, across different phases of illness (symptom stabilization or exacerbation) or therapeutic intervention, through longitudinal follow-up of patients being monitored within the recruiting center. Finally, in a more exploratory manner, the investigators aim to investigate the neural correlates of the identified cognitive impairments.

The overall aim of this project is to monitor everyday life activity of children with neurological disorders undergoing rehabilitation using wearable sensors capable of accurate and unobtrusive long-term measurement. Specific objectives: 1. To adapt the sensors for the use by children with neurological disorders. The focus lies on the exact positioning and the investigation of the needed amount of IMUs. 2. To validate the sensor data with collected video recordings and to develop specific algorithms to automatically extract specific movements and to analyze long-term sensor recordings. 3. To perform a cross-sectional study to assess intensity, task-specificity and duration of upper and lower limb activity during rehabilitation. There, we aim to gain objective information about levels and types of activity during rehabilitation in relation to age, gender and disorder. 4. To conduct a responsiveness study to assess whether or not the sensor output is able to highlight changes over time during rehabilitation. Therefore, at time point T=0 (shortly after admission to our center), participants are equipped with 3 inertial measurement units (1 at each wrist and 1 at the sternum). Additionally, a small wearable camera is mounted to the chest. The participants then return to their everyday life for 4 hours (no therapies, measurement period is in the evening). Afterwards, the equipment is removed again. To investigate responsiveness, the same protocol is being repeated 4 weeks later (time point T=1).
