Traumatic Brain Injury

A traumatic brain injury may be mild, or it may be more severe. Common causes of traumatic brain injury may include a motor vehicle accident, a blow to the head, force from a blast, or a stroke.

Cognitive and physical symptoms can vary widely depending on the injured part of the brain. A neuropsychological assessment can help to determine what aspects of your thinking abilities have been affected by the injury, how severe the symptoms are, and provide recommendations to assist in optimal recovery.

If you’ve suffered a traumatic brain injury, it is a good idea to go to the hospital or speak with your doctor to request a CT head scan.

Stroke

A stroke is a type of brain injury that is caused by a blood clot or a ruptured blood vessel in the brain. Neuropsychological assessment can help to determine what aspects of your thinking abilities have been affected by the stroke, how severe the symptoms are, and provide recommendations to assist in optimal recovery.

  • An ischemic stroke is caused by a blood clot that disrupts blood flow to the brain, depriving the brain of oxygen and nutrients. If left untreated, this can result in permanent damage and changes in cognitive functioning.
  • A hemorrhagic stroke is caused by bleeding in the brain and can result in permanent damage and changes in cognitive functioning.
  • A Transient Ischemic Attack (TIA) is a temporary decrease in blood flow to part of the brain. The symptoms may be similar to those of a stroke but are temporary. If you’ve had a TIA in the past, you may be at greater risk of a stroke.

If you think you or someone you are with is having a stroke, call 9-1-1 as this is a medical emergency.

Concussion

A concussion is a type of traumatic brain injury that can affect your brain functioning. The effects of a concussion are usually temporary and may include headache, nausea, dizziness, fatigue, and a feeling of “brain fog.”

Usually, these symptoms resolve quickly, but some people experience persistent difficulties following a concussion.

Neuropsychological assessments can help determine a baseline level of attention, memory, and mental speed for individuals who engage in contact sports where a concussion is more likely. This assessment may also help with recommendations regarding returning to work or sports after a concussion.

Dementia

The medical term for a dementia is a Neurocognitive Disorder. There are several different types of dementia, and the specific cognitive deficits that someone experiences will depend on the reason that a dementia has occurred.
  • Alzheimer’s disease is the most commonly known type of dementia and primarily involves memory problems.
  • Vascular Neurocognitive Disorder can occur when there are changes to the blood vessels in the brain.
  • Frontotemporal dementia often involves changes in language or behaviour.
  • Other causes of dementia may include Lewy Bodies or medical conditions such as Parkinson’s disease, Huntington’s disease, or HIV.
  • Sometimes, stress, anxiety, or depression may cause symptoms that can look like dementia. This may be referred to as a pseudodementia.
Neuropsychological assessment can provide a more accurate and earlier diagnosis of dementia than medical tests alone, particularly when there are few physical symptoms associated with the cognitive changes. Early neuropsychological assessment provides a starting point that allows health care providers to track changes in cognitive function over time. Results can guide medical decision making and help with personal decisions such as managing finances, living arrangements, driving, or other day-to-day activities.

Neurodevelopmental Disorders

Neurodevelopmental disorders begin in childhood. Children with neurodevelopmental disorders often have problems at school. Adults may struggle with social relationships and with performance at work.

People with Attention Deficit/Hyperactivity Disorder (ADHD) may have persistent problems paying attention, organizing tasks and activities, restlessness, controlling impulsive behaviour, or keeping that inside voice on the inside.

Autism is a neurodevelopmental condition caused by differences in the way the brain develops. People on the Autism spectrum may have problems with social communication, emotional regulation, or sensory processing.

Other neurodevelopmental conditions that may be diagnosed through neuropsychological assessment include intellectual disability, or specific learning disabilities.

Medico-Legal Assessment (Independent Medical Evaluation; IME)

A Medico Legal assessment (also known as an Independent Medical Evaluation) is a specialized assessment that may be required if you have a legal or an insurance claim related to a change in your cognitive functioning after an accident. This assessment may be used to determine the extent of your injury and the effect that the injury has had on your life.

These assessments are independent, meaning that the neuropsychologist will provide an objective and unbiased opinion, and does not work specifically for any party involved in the litigation.

A Medico-Legal assessment may be requested by your lawyer, an insurance company, the insurance company’s lawyers, a government agency, WCB, or another organization. The medico-legal assessment report will be provided to the agency who requests the assessment.

Psychological Assessment

Dr. Chevalier has expertise in assessing and diagnosing mental health conditions such as depression, anxiety, bipolar disorder, PTSD, personality disorders, and schizophrenia.

Often, severe mental illness is associated with cognitive problems that can be measured through neuropsychological assessment.

Consultation Services

Consultations are services that are not direct treatment or assessment but can help a person, agency, or another health care provider with a question they may have. A consultation may involve discussing whether an assessment is appropriate for a particular condition or individual, discussing treatment options, or reviewing the results of a previous assessment. It may also involve providing education regarding the meaning and implications of a particular diagnosis, explaining the general format and purpose of an assessment, or assisting in implementing treatment.
