Question 1: Describe the diagnostic criteria of osteoarthritis versus rheumatoid arthritis
Osteoarthritis (OA) and rheumatoid arthritis (RA) are distinct forms of arthritis, each possessing unique diagnostic criteria. Osteoarthritis, a degenerative joint disease, primarily affects cartilage, the protective tissue cushioning the ends of bones. Its diagnosis often involves a combination of physical examination findings, imaging studies, and patient-reported symptoms. Radiographic evidence of joint space narrowing, osteophyte formation (bone spurs), and subchondral sclerosis (bone thickening) are common indicators (Hunter & Bierma-Zeinstra, 2019). Patients typically experience pain exacerbated by activity and relieved by rest, along with stiffness, limited range of motion, and crepitus (grating sensation) in the affected joints.
Rheumatoid arthritis, conversely, is a systemic autoimmune disease characterized by chronic inflammation of the synovium, the membrane lining the joints. Diagnosis relies on a constellation of factors, including clinical presentation, serological tests, and imaging. The American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria incorporate joint involvement, serological markers (rheumatoid factor and anti-cyclic citrullinated peptide antibodies), acute phase reactants (C-reactive protein and erythrocyte sedimentation rate), and symptom duration (Neogi et al., 2010). RA typically manifests as symmetrical joint pain, swelling, and stiffness, often affecting the small joints of the hands and feet. Systemic symptoms such as fatigue, fever, and weight loss may also occur.
Question 2: Discuss types of headaches and their treatment
Headaches, a common ailment, encompass various types, each with specific characteristics and treatment approaches. Tension-type headaches, the most prevalent form, present as a dull, aching pain often described as a tight band around the head. Over-the-counter pain relievers like ibuprofen or acetaminophen, along with stress management techniques, typically suffice for treatment.
Migraines, another frequent type, manifest as severe, throbbing headaches, often accompanied by nausea, vomiting, and sensitivity to light and sound. Treatment options include nonsteroidal anti-inflammatory drugs (NSAIDs), triptans (specific migraine medications), and preventive therapies such as beta-blockers and anticonvulsants (Dodick et al., 2018).
Cluster headaches, though less common, are characterized by excruciating, unilateral pain around the eye or temple, occurring in clusters over weeks or months. Acute treatment involves oxygen therapy, triptans, and local anesthetics. Preventive strategies include verapamil, corticosteroids, and nerve blocks. Secondary headaches arise from underlying medical conditions such as sinus infections, head injuries, or brain tumors. Treatment focuses on addressing the underlying cause.
Question 3: Discuss types of seizures and treatment
Seizures, transient episodes of abnormal brain activity, manifest in diverse ways depending on the affected brain region and seizure type. Focal seizures originate in a specific area of the brain and may involve motor symptoms (jerking movements), sensory disturbances (tingling or hallucinations), or cognitive changes (confusion or altered awareness). Generalized seizures involve both hemispheres of the brain and can present as tonic-clonic seizures (grand mal seizures) with loss of consciousness and convulsions, absence seizures (petit mal seizures) with brief staring spells, or myoclonic seizures with sudden muscle jerks.
Treatment for seizures typically involves antiepileptic drugs (AEDs) such as levetiracetam, lamotrigine, and valproic acid (Moshé et al., 2015). The choice of AED depends on the seizure type and individual patient factors. In cases where medication fails to control seizures, surgical intervention, vagus nerve stimulation, or dietary therapies like the ketogenic diet may be considered.
Question 4: Discuss Parkinson’s disease, its causes, symptoms, and treatment
Parkinson’s disease (PD), a progressive neurodegenerative disorder, primarily affects movement. It arises from the degeneration of dopamine-producing neurons in the substantia nigra, a region of the brain involved in motor control. While the exact cause remains elusive, a combination of genetic and environmental factors is thought to contribute.
The cardinal symptoms of PD include tremor, rigidity, bradykinesia (slowness of movement), and postural instability. Non-motor symptoms such as sleep disturbances, depression, and cognitive impairment may also occur. Treatment aims to manage symptoms and improve quality of life. Levodopa, a precursor to dopamine, remains the cornerstone of PD therapy. Other medications, including dopamine agonists, MAO-B inhibitors, and COMT inhibitors, may be used in conjunction with levodopa or as monotherapy. Deep brain stimulation, a surgical procedure involving the implantation of electrodes in the brain, can provide significant benefit for some individuals with advanced PD.
