Detaljeret beskrivelse
This study is being done to learn if a new brain imaging technology called DaTscan can detect subtle changes in the brain ("biomarkers") that are similar to those seen in early Parkinson's disease (PD). The results of this study may provide more information about a potential link between mild to moderate traumatic brain injury (mTBI) and PD. We will compare findings from persons who experienced mTBI ("cases") to persons without history of brain injury (mTBI-or "controls"). This study may provide preliminary data that might be used to help design future long-term studies.
The investigators propose scientific studies with one specific aim and two hypotheses:
Specific aim: to determine if one year post emergency room (ER) visits, DaTscan uptake (Ioflupane I123 injection and single photon emission computerized tomography) is lower in subjects exposed to mTBI (defined as a closed head trauma that results in loss of consciousness or amnesia for less than 24 hours) than in subjects not exposed to mTBI (without closed head trauma; mTBI-).
Hypotheses:
Hypothesis #1: mTBI is a risk factor for Parkinson's disease (PD). Hypothesis #2: DaTscan is able to detect subclinical PD (as measured by a dopamine transporter deficiency) in mTBI subjects.

mTBI
Historical cohort of subjects seen in the emergency rooms of NorthShore University HealthSystem with ICD-9 diagnoses of mild or moderate traumatic brain injury during the years 2006-2011 (7,122 subjects).
100 mTBI+ subjects are randomly selected for clinical assessment and DaTscan.

mTBI-
Historical cohort of subjects seen in the emergency rooms of NorthShore University HealthSystem with ICD-9 diagnoses of disorders other than mild or moderate traumatic brain injury during the years 2006-2011 (7,122 subjects).
100 mTBI- subjects are randomly selected for clinical assessment and DaTscan.

clinical assessment
Tidsramme: At least one year post ER visit for mTBI or mTBI-
|
All subjects complete a questionnaire that documents lifelong exposures to mTBI; that screens for parkinsonism, Parkinson's disease, or tremor; and that screens for DaTSCAN exclusion criteria.
We abstract medical records.
Subjects eligible for DaTSCAN undergo the Montreal Cognitive Assessment (MoCA); Ohio State University TBI Identification Method Short Form (OSU-TBI-ID-SF); General Anxiety Disorder 7-item Scale (GAD7); Center for Epidemiological Studies Depression Scale (CES-D); Rivermead Post Concussion Symptoms Questionnaire; Insomnia Severity Index (ISI); World Health Organization Quality of Life-Brief Assessment (WHOQOL-BREF); Review of Systems; Past Medical History; Detailed Examination of Motor Function-Unified Parkinson's Disease Rating Scale (UPDRS part III); Neurological Examination; Syndromic Classification (parkinsonism, essential tremor, mild cognitive impairment); Differential Diagnosis of Parkinsonism (if applicable); Final Diagnosis of Parkinsonism (if applicable).
