  • EFA; epilepsy foundation of americaAES; american epilepsy societyMAB; medical advisory board # The conclusions from this study suggested that the overall crash rate was low and that a 6 month SFI was associated with a lower crash rate than a shorter SFI. Crashes related to seizures and other medical conditions are uncommon but when they occur they are often sensationalized in the popular press.# In Arizona, the SFI was reduced from 12 to 3 months without a significantly increased number of seizure related crashes or deaths
  • n addition to the typical motor symptoms of Parkinson disease (PD), persons with PD may develop cognitive impairment/dementia, emotional impairments (e.g., apathy and disinhibition), and visual-perceptual deficits that often do not respond to dopaminergic medications.

    5. 5. Driving  Higher cognitive functions  Perception and attention to stimulus  Formulation of a plan based on memory experiences  Execution of an action such as applying a brake, steering control, or accelerator  Vision  motor control and coordination.

    8. 8. Pros & Cons on reporting  Patient’s safety  Community safety  Doctor-patient confidentiality  Patient conceal medical information that help in treatment  Patient’s right
    9. 9. Epilepsy
    10. 10. Studies showed  Approximately 700,000 of the 180 million1 Americans     licensed to drive have epilepsy Drivers with well-controlled seizures are not at a high or unacceptable risk for crashes uncontrolled epilepsy poses a substantial risk for MVA 50% patients who have seizures while driving have motor vehicle crashes One recent US study showed that patients with intractable seizures often continue driving.  39% had a seizure at the wheel  27% crashed because of a seizure

Evidence-based Not predictive of motor vehicle crash (MVC). protective against crashes Short seizure-free intervals (≥ 3 months) (Level C) Epilepsy surgery (Level B), Seizure-free intervals (6– 12 months) (Level B) Few prior non-seizurerelated crashes (Level B) Regular antiepileptic drug adjustments (Level B) Epilepsy Behav. 2012 Feb;23(2):103-12

    13. 13. Seizure-free period & Driving  Most European countries; 1 yr seizure-free  In USA: AAN – AES –EFA; 3 months  3 months (7 states), 6 months (14 states), and 1yr (7 states)  23 state no specific time [Neurologist – MAB]  7 states mandatory physician reporting  In Japan: 1 yr seizure-free

    20. 20. Dementia
    21. 21. Dementia and driving  Patients with mild AD showed double car crash in age-matched controls.  The average number of crashes per year in patients with AD increased dramatically after the first 3 years from symptom onset.  75% can pass on-road driving
    22. 22. Evidence-Based : patients at increased risk for unsafe driving Factor Clinical Dementia Rating Scale [CDR] A caregiver's rating of a patient's driving ability as Level of evidence A C marginal or unsafe A history of traffic citations A history of crashes Reduced driving mileage Self-reported situational avoidance MMSE scores of ≤24 Aggressive or impulsive personality characteristic C C C C C C AAN Practice Parameter update: Evaluation and management of driving risk in dementia 2010

    24. 24. Stroke
    25. 25. Driving after stroke  In developed countries, more than half of persons with stroke are fit to drive following a successful onroad examination  Most reliable test for recognition of resuming driving after stroke:  Road Sign Recognition test  Trail making test B  Compass task  Cube copy test  Stroke Drivers Screening Assessment
    26. 26. Parkinson’s Disease
    27. 27. Parkinson disease (PD): Typical motor symptoms Cognitive impairment/dementia Emotional impairments (e.g., apathy and disinhibition)  Visual-perceptual deficits Possible side effects (e.g., daytime sleepiness) of PD medications
    28. 28. Parkinson’s D & driving  A retrospective survey study: found that patients with Hoehn & Yahr (H&Y) stages 2 and 3 had a significantly higher crash risk compared to healthy controls. However, there was no evidence of increased crash risk among patients in H&Y stage 1 Another survey study: 82% of patients with PD held a driving license and 60% of them were still driving. Of the patients holding a driving license, 15% reported being involved in an accident. Drivers with PD may not reveal medical information when renewing their license or adhere to physician's advice to quit driving.
    29. 29. Evidence- Based
    30. 30. Tying it all together!  Neurological disorders are most frequent cause for driving disability  Most studies focus on epilepsy and dementia followed by parkinson’s D  For epilepsy most studies and regulations focus on seizure-free period before allowing to drive again  For dementia ; evidence- based guidelines are available to help the physician to take his decision
