Study Notes
Neurological Disorders
-
Clinical Significance in Dentistry:
- Cerebrovascular accidents (stroke)
- Epilepsy
- Alzheimer's
- Parkinson's
- Multiple Sclerosis
- Cerebrospinal Fluid (CSF) shunts
- Cranial nerve abnormalities
-
Potential complications for patients with neurologic diseases in a dental clinic:
- CVA (stroke)
- Altered consciousness
- Adverse bleeding
- Myocardial infarction (heart attack)
- Infective endocarditis
Stroke
-
Definition: Sudden obstruction or rupture of the blood supply to the brain.
-
Types:
- Ischemic stroke: Clot blocks blood flow.
- Hemorrhagic stroke: Bleeding occurs inside or around brain tissue.
- TIA (transient ischemic attacks): Temporary blockage of an artery, lasting less than 24 hours; a “mini-stroke."
-
Symptoms:
- Sensory, motor, autonomic, or complex function impairments
- Slurred speech
- Weak muscles
- Difficulty swallowing
- Loss of speech
- Unilateral paralysis
- Loss of sensory stimuli
- Flaccid tongue (weak and limp)
-
Risk factors:
- Men
- Increasing age
- Smoking
- Obesity
- Heavy alcohol use
Taking History
- Importance: A history is crucial because one in three people who have a stroke are at risk for another stroke within one month.
-
History for patients who have already had a stroke:
- The risk of a recurrent stroke is elevated for at least six months.
Periodontal Disease and Stroke
- Link: Calcified atherosclerotic plaques (hardening of arteries) are visible on panoramic X-rays. Carotid calcifications (in the neck) are linked to future vascular events.
- Association with Periodontitis: Patients with periodontitis are at increased risk of stroke, especially ischemic events.
- Bone Loss: Severe periodontal bone loss is linked to carotid artery plaques and stroke risk.
Multiple Sclerosis
- Definition: An autoimmune disease that affects the protective covering of nerve fibers (myelin). The immune system mistakenly attacks the myelin, causing inflammation, damage, and scar tissue formation.
- Location: Most commonly affects the central nervous system (CNS) and not the peripheral nervous system (PNS).
-
CNS Areas affected:
- Optic nerve
- Cerebral white matter
- Cervical spinal cord
- Stages: Marked by phases of relapse (symptoms worsen) and remission (symptoms improve).
- Treatment: Treatment is most effective during remission phases.
Parkinson's disease
- Definition: A progressive neurodegenerative disorder that affects movement, causing tremors, stiffness, and impaired coordination.
- Cause: Caused by the death and depletion of dopamine-producing cells in the brain.
- Dopamine and Movement: Dopamine (a neurotransmitter) plays a crucial role in the nigrostriatal pathway, which coordinates voluntary movements.
-
Symptoms: TRAP:
- Tremor
- Rigidity
- Akinesia (slowness of movement)
- Posture/balance problems
-
Other symptoms:
- Masklike appearance
- Excessive sweating
- Drooling
- Gait with rapid, short shuffling steps and reduced arm swinging.
Dental Management of Parkinson's Disease
- Challenges: Parkinson's disease impairs oral hygiene tasks and affects coordination during dental procedures.
-
Key concerns:
- Minimizing adverse outcomes: Muscle rigidity and tremors.
- Avoiding drug interactions: Certain medications can interact with dental medications.
- Scheduling: Short appointments and stress-reducing measures can improve patient outcomes.
Cranial Nerves
-
Trigeminal nerve (CN V):
- Sensory for the face.
-
Facial nerve (CN VII):
- Motor nerve for the face.
