Understanding the Differences: GP, PMR, Neurology, and Neuropsychology in IMEs

For insurers, legal professionals, and employers, understanding the distinctions between a General Practitioner (GP), a Physical Medicine & Rehabilitation (PMR) specialist, a Neurologist, and a Neuropsychologist can help ensure that the right questions are answered with clarity and authority.

When it comes to Independent Medical Examinations (IMEs), selecting the right specialist is critical. Each expert brings a unique scope of practice and expertise to the assessment process. 

Below, we break down these specialties and their roles within IMEs.

General Practitioner (GP)

A General Practitioner is often the first point of contact in the healthcare system. GPs provide broad, generalist care and have a wide knowledge base across multiple areas of medicine.

In the context of IMEs:

• GPs are well-suited for assessments requiring a general medical overview or when the issues are not tied to a specific specialty.
  
  
• They may provide opinions on work capacity, functional limitations, and medical stability from a broad clinical perspective.
  
  
• They may refer complex or highly specialized concerns to a more focused medical specialist.

Example:  A GP is well positioned to complete an assessment of an individual’s overall health. The IME may explore lifestyle factors, chronic disease management (i.e., diabetes, sleep apnea, thyroid dysfunction, etc.) or mental health screening.  

Physical Medicine & Rehabilitation (PMR) Specialist

Also known as Physiatrists, PMR specialists focus on restoring function in people with physical impairments, injuries, or disabilities. Their expertise bridges medicine and rehabilitation, with a strong emphasis on functional outcomes.

In the context of IMEs:

• Physiatrists diagnose and treat conditions that affect movement, pain, and overall function. This may include injuries or illnesses affecting the nerves, muscles, bones, brain and other parts of the musculoskeletal and nervous system.
  
  
• They assess functional capacity and provide recommendations for rehabilitation, workplace accommodations, and return-to-work planning utilizing non-surgical methods.
  
  
• Their role is to focus on restoring physical function and mobility after injury, illness or disability.

Example: In a workplace injury involving repetitive strain or a spinal injury, a PMR specialist will complete a comprehensive neuromusculoskeletal assessment to comment on treatment recommendations or return to work recommendations. 

Neurology

Neurologists specialize in diagnosing and managing conditions of the brain, spinal cord, and peripheral nervous system. Their training emphasizes the biological and structural aspects of neurological disease.

In the context of IMEs:

• Neurologists are called upon when there is suspicion of nerve or brain injury, such as concussions, strokes, seizures, or neuropathies.
  
  
• They provide insight into the underlying neurological cause of symptoms and help determine prognosis.
  
  
• Their assessments are valuable in cases involving traumatic brain injury, neurological impairment following an accident, or progressive neurological disorders.

Example: In a motor vehicle accident case where a claimant reports ongoing headaches and numbness/tingling, a Neurologist would assess whether these are consistent with a concussion and a central or peripheral neuropathy.

Neuropsychology

Neuropsychologists are clinical psychologists with specialized training in how brain function affects behaviour, cognition, and emotion. They do not prescribe medication but instead use standardized tests to evaluate brain-behaviour relationships.

In the context of IMEs:

• Neuropsychologists assess cognitive function, memory, attention, problem-solving, and emotional regulation. They provide evidence-based insight into the psychological and cognitive consequences of brain injuries or neurological conditions.
  
  
• Their assessment may include clinical interviews and completion of standardized tests.
  
  
• Their reports can clarify whether difficulties are related to genuine cognitive impairment, psychological distress, or non-organic factors. 

Example: In a case assessing a queried post-concussion syndrome, a Neuropsychologist may conduct a battery of tests to determine whether cognitive symptoms are consistent with a brain injury or better explained by psychological or emotional factors.

Why Choosing the Right Specialist Matters in IMEs

Each of these specialties brings a different, but complementary, lens to medical assessment. The choice depends on the nature of the condition, the questions being asked, and the evidence needed:

• GP → Broad medical overview and general health conditions
  
  
• PMR → Function, rehabilitation, musculoskeletal and pain conditions
  
  
• Neurology → Neurological disease, structural or nerve-based conditions
  
  
• Neuropsychology → Cognitive and psychological impacts of brain function
