Study Notes
Nervous System Disorders
- A physical condition that affects the Central Nervous System (CNS) and the Peripheral Nervous System (PNS)
- Common CNS disorders include brain tumours, encephalitis, epilepsy, meningitis, multiple sclerosis, Alzheimer’s, Parkinson’s, and Huntington’s disease
- Common PNS disorders include peripheral neuropathy, diabetic polyneuropathy, Guillain-Barre syndrome, and sciatica
- Causes include congenital defects, vascular issues, infections (fungal, viral, bacterial, parasitic), degenerative diseases, trauma, environmental factors, habits, other health conditions, gender, age, and genetics
- Presenting symptoms include pain, muscle malfunction, changes in sensation, changes in the special senses, sleep problems, changes in consciousness, changes in cognition, dysphagia, dysarthria
- Dental considerations are medication side effects, medication interactions, consent, access, compliance with treatment, behaviour management, impaired memory, and additional equipment
Dental Implications
- Dental professionals should educate patients on the potential impact of nervous system disorders on dental treatment
- Patients with nervous system disorders may be more susceptible to dental complications, and thus require more frequent dental checkups
- Patients might have difficulty managing their oral hygiene, making it essential to provide additional support and instruction
- Modifications to treatment plans may be necessary to address patient specific needs and provide appropriate care
- Dental professionals should be aware of the potential for medication interactions and side effects, and take them into consideration when providing dental care
Presentation
- Students are tasked with creating a presentation on a specific nervous system disorder
- The presentation must include a definition, cause, treatment, dental implications, and modified dental treatment considerations
- Students will create a poster design which can include a mind map, PowerPoint slides, or a combination of both
- All sources must be properly referenced
Nervous System Disorders: An Overview
- Nervous system disorders affect either the central nervous system (CNS) or the peripheral nervous system (PNS), causing disruptions in physical, cognitive, and sensory functions.
Central Nervous System Disorders
- CNS includes the brain and spinal cord.
- Brain Tumors: Abnormal growths in the brain, causing various symptoms like headaches and seizures.
- Encephalitis: Brain inflammation, often caused by infections, leading to fever and potential coma.
- Epilepsy: Recurrent seizures due to abnormal electrical activity in the brain.
- Meningitis: Inflammation of the membranes covering the brain and spinal cord (meninges), often due to infection, causing a stiff neck and fever.
- Multiple Sclerosis (MS): Progressive disease affecting the myelin sheath, causing weakness and coordination problems.
- Alzheimer’s Disease: Neurodegenerative condition causing memory loss and significant cognitive decline.
- Parkinson’s Disease: Progressive disorder affecting movement, characterized by tremors and slow movement.
- Huntington’s Disease: Genetic disorder causing the breakdown of nerve cells, leading to movement disorders and cognitive decline.
Peripheral Nervous System Disorders
- PNS comprises nerves outside the brain and spinal cord.
- Peripheral Neuropathy: Damage to peripheral nerves, causing pain, numbness, and weakness in limbs.
- Diabetic Polyneuropathy: Nerve damage caused by high blood sugar levels in diabetics, leading to sensory loss and potential foot ulcers.
- Guillain-Barré Syndrome: Immune system attacking peripheral nerves, causing muscle weakness and paralysis.
- Sciatica: Compression of the sciatic nerve, resulting in lower back pain radiating down the legs.
- Facial Nerve Paralysis (Bell’s Palsy): Sudden weakness or paralysis of facial muscles, often on one side, due to facial nerve damage.
Causes of Nervous System Disorders
- Congenital: Conditions present at birth, such as cerebral palsy.
- Vascular: Impaired blood flow, leading to stroke or aneurysm.
- Infections: Bacterial (meningitis), viral (encephalitis), fungal, or parasitic infections can cause nervous system damage.
- Degenerative: Progressive cell damage, as seen in Alzheimer’s and Parkinson’s disease.
- Trauma: Physical injury, such as traumatic brain injury (TBI) or spinal cord injury.
- Environmental Factors: Exposure to toxins like heavy metals or alcohol.
Risk Factors
- Lifestyle factors like smoking and poor diet, co-morbidities like diabetes and hypertension, age, genetics, and gender.
Symptoms of Nervous System Disorders
- Pain: Common symptom in conditions like neuropathy and sciatica.
- Muscle Malfunction: Weakness, loss of coordination, or involuntary movements (tremors or spasticity).
- Changes in Sensation: Numbness, tingling, or loss of sensation, often seen in peripheral neuropathies.
- Special Sensory Changes: Vision (blurred or double vision in MS), hearing loss, or taste changes.
- Sleep Problems: Disrupted sleep cycles, leading to insomnia or excessive sleepiness.
- Consciousness Changes: Seizures, loss of consciousness, or cognitive slowing.
- Cognitive Changes: Memory loss, confusion, language difficulties, and impaired judgment.
Dental Considerations for Neurological Patients
- Medication Side Effects: Common medications for neurological conditions may cause dry mouth, bleeding, or increased infection risk.
- Medication Interactions: Be cautious of interactions between neurological medications and dental medications.
- Consent: Patients with cognitive disorders may struggle with providing informed consent.
- Access: Patients with mobility issues need assistance moving in and out of the dental chair.
- Compliance: Neurological disorders may impair a patient’s ability to comply with oral hygiene practices.
- Behaviour Management: Patients with anxiety or involuntary movements may require patience and reassurance.
- Impaired Memory: Patients may forget appointments or oral hygiene instructions.
- Special Considerations and Equipment: Tailor dental treatments with consideration for physical impairments, using mouth props or adaptive tools.
