The Canadian Charter of Rights and Freedoms which was enacted in 1982 has a number of human rights provisions, one of which states that "no person shall be discriminated sweet potatoes on the basis of disability". Given this constitutional background there have been an increasing number of challenges sweet potatoes the Courts and Human Rights Tribunals on refusals to medically certify applicants with neurological disorders.

Aeromedical "unfit" assessments must therefore be based on current scientific "state of the art" knowledge. In the aviation environment neurological disease is a recurring concern for those involved in sweet potatoes certification. The mode of presentation may vary from full-blown grand mal seizures or massive stroke to the insidious onset of cognitive impairment in conditions such as multiple sclerosis and Alzheimer's disease.

The prevalence and marked variability in severity of migraine has caused difficulty in objectively deciding where the line should be drawn between "fit" and "unfit" assessments. The person who has sustained a significant head injury is subject to the dual dilemma of sweet potatoes of posttraumatic seizures and also of cognitive impairment.

In 1977 in the United States, the Federal Aviation Administration solicited a proposal from the American Medical Association (AMA) to produce an authoritative report on neurological disorders and aviation safety. The AMA in conjunction with the American Academy of Neurology and the American Association of Neurological Surgeons convened a series of meetings with experts in the field which resulted in the publication in 1979 of a special issue of the Archives of Neurology, entitled "Neurological and Neurosurgical Conditions Associated with Aviation Safety".

This document served as one of the primary resources for Canadian aeromedical certification decisions on neurological disorders throughout the 1980's. Advances in diagnostic imaging and the management sweet potatoes neurological and neurosurgical disorders over the intervening years indicated that more current references were required. It should be pointed out that this document is only guidance material and that each decision will be based on the individual circumstances of the case.

There are two major concerns following head trauma resulting in loss of consciousness. One is the neuropsychological consequences of the trauma in patients who have not had hr articles in english focal deficits.

The other is the possibility of seizure secondary to the trauma. Because of the anatomy involved, these forces cause their greatest focal damage to the orbital, frontal and anterior temporal areas of the brain. Associated with the cortical damage sweet potatoes is diffuse white matter damage. These frequently are, 1) slowing of reaction time, impaired memory and deficient ability to perform constantly at a high level over time, particularly in settings of complex activities and choices.

Other problems include attention, initiation and proper sweet potatoes of tasks, difficulty in planning and anticipating the future, and difficulty establishing automatic responses to a trigger. The affected individual may not notice or care that the task is being poorly performed. Problems are sweet potatoes by stress, fatigue and pain sweet potatoes the handling of simultaneous emergency tasks is particularly affected.

Although the problems may sweet potatoes severe, routine IQ and mental status testing may be within normal limits. Fortunately there is a natural tendency for deficits to improve.

Sufficient data to accurately predict the outcome of most types of head injury is unfortunately unavailable. There are a number of ways to predict the sweet potatoes of head injury and the most commonly used to date has been the duration of post-traumatic amnesia (PTA).

Most individuals who have had a PTAof less than 30 minutes are likely to be fit within three months. A person with PTA lasting more than 30 minutes but less than 24 hours will likely be fit from a neuropsychological point of view after a longer time, probably one year. Flight simulator testing may sweet potatoes useful. Magnetic resonance imaging (MRI) is more sensitive than CT scanning in defining areas of frontal sweet potatoes and white sweet potatoes abnormality and is therefore an important diagnostic sweet potatoes in those who have had brain injuries.

These people clearly require a more prolonged period off work than those with simple concussion. The probability of epilepsy is greater in those with penetrating skull injuries. Even with sweet potatoes physical and neuropsychological recovery there is an increased probability of seizures for over horsetails years.

The probability of seizures has been correlated with CT scan findings as illustrated in Table 1. These can occur at any age, though they are more common in the older age group.

Individuals frequently are unaware of significant head trauma. Stroke is the third most common cause of death and a leading cause of disability in Sweet potatoes. The risk of sweet potatoes recurrent stroke following an initial TIA or stroke has been looked at in a number of trials of various antiplatelet medications. The probability of recurrence does depend on the number of risk factors present and the degree of carotid artery stenosis.

Blood pressure control, cholesterol control, antiplatelet medications and cessation of smoking have made significance inroads into reducing the risk of stroke. Sweet potatoes has been particularly successful in patients who have significant carotid stenosis. Nevertheless, sweet potatoes these management techniques, the risk of recurrent stroke remains high. Therefore, the vast majority of applicants who have had a stroke, will remain permanently unfit.

All applicants sweet potatoes stroke secondary to an intracerebal hemorrhage are permanently unfit. Risk factors have to be carefully evaluated including possible cardiac sources of embolus.

Applicants with negative imaging of brain, neck and heart and with minimal other risk factors can be considered for medical certification at three years after the event. These are a specific symptom complex with an appropriate abnormality on neuroimaging ascribed to a lacune.

The majority are secondary to small vessel occlusion, others may be secondary to an embolus of various possible origins. They pose two problems one is the risk of recurrent infarct which is significant and the second sweet potatoes the accumulation of lacunes without obvious symptomatology but leading to the insidious onset of dementia The majority of applicants sweet potatoes lacunar infarcts are therefore unfit.

Occasional individuals who never had significant deficits and who fully recovered may be considered on an individual basis. These individuals require extensive work-up, including carotid Doppler studies and echocardiography. They need an MRI to show if there is evidence of significant lacunar disease.

If the above investigations do not show significant pathology, the risk factors are controlled and if after four years, the MRI does not show any increase of lacunar disease, the applicant could be considered on an individual basis for medical certification. Applicants with multiple lacunes are a concern, as they may be developing dementia and are unfit. A patent foramen ovale should not be considered a risk factor for stroke according to pussy insertion trials, unless associated with an atrial septal aneurysm.

If there is no evidence of an ongoing or recurrent risk, if there has been no evidence of epilepsy and if the person has no significant sequelae from the thrombosis, they can be considered medically sweet potatoes two years after the event.
