    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.
