Neurological Disorders
Types of Neurological Disorders
- Cerebrovascular disorders include stroke, transient ischemic attack (TIA), and vasculitis, which affect blood flow to the brain.
- Demyelinating disorders, such as multiple sclerosis, Guillain-Barré syndrome, and chronic inflammatory demyelinating polyneuropathy, damage the protective covering of nerve fibers.
- Infections like meningitis, encephalitis, and brain abscess can cause neurological problems.
- Neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), involve progressive nerve cell damage.
- Neuromuscular disorders, such as myasthenia gravis, muscular dystrophy, and peripheral neuropathy, affect muscle and nerve function.
- Seizure disorders, including epilepsy, febrile seizures, and status epilepticus, involve abnormal brain electrical activity.
- Sleep disorders, like insomnia, sleep apnea, and narcolepsy, affect normal sleep patterns.
- Trauma and injury, including concussion, traumatic brain injury, and spinal cord injury, can cause neurological problems.
Causes and Risk Factors
- Genetics play a role in neurological disorders, with family history and genetic mutations increasing risk.
- Lifestyle factors, such as smoking, physical inactivity, poor diet, and substance abuse, can contribute to neurological disorders.
- Infections, including bacterial, viral, and fungal infections, can trigger neurological problems.
- Trauma, such as head and spinal cord injuries, can cause neurological disorders.
- Environmental toxins, like heavy metals, pesticides, and industrial chemicals, can increase risk.
- Age is a significant risk factor, with many neurological disorders more common in older adults.
Symptoms and Diagnosis
- Symptoms of neurological disorders vary, but may include weakness, numbness, or paralysis, as well as seizures, tremors, or muscle spasms.
- Cognitive impairment, speech and language difficulties, and swallowing problems are also common symptoms.
- Neurological disorders can cause headaches, fatigue, and sleep disturbances.
- Diagnostic tests include imaging studies like CT, MRI, and PET scans, as well as electrophysiological tests like EEG, EMG, and NCV.
- Blood tests, biomarkers, genetic testing, and clinical evaluation are also used to diagnose neurological disorders.
Neurological Disorders
Cerebrovascular Disorders
- Stroke is a sudden loss of brain function due to interruption of blood flow to the brain
- There are two main types of strokes: ischemic stroke (blood vessel blockage) and hemorrhagic stroke (blood vessel rupture)
- Transient Ischemic Attack (TIA) is a temporary stroke-like symptom that often serves as a warning sign for an impending stroke
Demyelinating Disorders
- Multiple Sclerosis (MS) is a chronic autoimmune disease that causes demyelination of CNS nerve fibers
- MS symptoms include vision problems, muscle weakness, numbness, and cognitive impairment
- Guillain-Barré Syndrome is a rapid-onset muscle weakness often following an infection
Infectious Disorders
- Meningitis is an inflammation of the meninges, often caused by bacterial or viral infections
- Meningitis symptoms include headache, fever, stiff neck, and photophobia
- Encephalitis is an inflammation of the brain, often caused by viral infections
- Encephalitis symptoms include fever, headache, and altered mental status
Movement Disorders
- Parkinson's Disease is a neurodegenerative disorder affecting movement, balance, and coordination
- Parkinson's Disease symptoms include tremors, rigidity, bradykinesia, and postural instability
- Huntington's Disease is an inherited disorder causing progressive damage to the brain
- Huntington's Disease symptoms include chorea, cognitive decline, and psychiatric disturbances
Neurodevelopmental Disorders
- Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder affecting communication, social interaction, and behavior
- ASD symptoms include delayed language development, social difficulties, and repetitive behaviors
- Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder affecting attention, impulse control, and motor activity
- ADHD symptoms include inattention, hyperactivity, and impulsivity
Neuropathic Pain Disorders
- Neuropathic Pain is a chronic pain resulting from nerve damage or dysfunction
- Causes of Neuropathic Pain include diabetes, shingles, nerve injury, and chemotherapy
- Complex Regional Pain Syndrome (CRPS) is a chronic pain disorder affecting a limb, often following trauma
- CRPS symptoms include burning pain, swelling, and skin changes
