📌 Hypercalcemia – Causes Made Easy (CHIMPANZEES) 🦍 Mnemonic: CHIMPANZEES C – Calcium supplementation H – Hyperparathyroidism (most common outpatient cause) I – Iatrogenic causes; Immobilization M – Multiple myeloma; Milk-alkali syndrome P – Parathyroid hyperplasia A – Alcohol-related causes N – Neoplasms (most common inpatient cause) Z – Zollinger-Ellison syndrome E – Excess Vitamin D E – Excess Vitamin A S – Sarcoidosis 💡 Quick Clinical Pearls 🔹 Hyperparathyroidism and malignancy account for most cases of hypercalcemia. 🔹 Classic symptoms: "Stones, Bones, Groans, Thrones & Psychiatric Overtones" 🪨 Kidney stones 🦴 Bone pain 🤢 Abdominal pain, constipation 🚽 Polyuria (frequent urination) 🧠 Confusion, depression, lethargy 🔹 ECG finding: Shortened QT interval ❤️ 🔹 Emergency treatment: IV normal saline 💧 Calcitonin 🩺 Bisphosphonates (e.g., Zoledronic acid) 💉 📚 Exam Tip: When a question mentions high calcium + bone pain + anemia + renal failure, think Multiple Myeloma first.

❇️ Common Headache Types ▶️ Stress Headache (Tension-type) → Pain forms a tight band around the forehead and back of the head → Dull, aching sensation → Often triggered by stress, poor posture, or fatigue ▶️ Migraine → Intense, throbbing pain on one side of the head → Often associated with nausea, sensitivity to light/sound → Can have visual auras before the headache starts ▶️ Hypertension Headache → Pain usually at the back of the head or neck → Often pulsating and occurs during high blood pressure spikes → May worsen with physical activity ▶️ Cluster Headache → Severe pain around one eye → Occurs in clusters (repeated over weeks/months) → May cause tearing, nasal congestion on the same side ▶️ Sinus Headache → Pain and pressure around the forehead, cheeks, and nose → Often worsens with movement or bending down → Usually accompanied by sinus infection symptoms (e.g., nasal congestion) ▶️ Post-Traumatic Headache → Develops after a head injury → Pain can be localized or widespread → May be accompanied by dizziness or memory issues ▶️ TMJ Headache → Pain near the temples or jaw joint → Associated with jaw clenching, grinding, or TMJ disorder → Can radiate to ear or neck ▶️ Exertion Headache → Triggered by physical activity (exercise, coughing, sex) → Throbbing pain often at the front or sides of the head → Usually short-lasting but intense ▶️ Thunderclap Headache → Sudden, severe headache that reaches peak intensity within seconds → Medical emergency—can indicate bleeding in the brain or aneurysm → Requires immediate medical attention

🧠 Parkinson’s vs Huntington’s — Know the Difference ⸻ 1️⃣ Parkinson’s Disease 🔸 Mnemonic: TRAP • Tremor → resting (“pill-rolling”) • Rigidity → cogwheel • Akinesia / Bradykinesia • Postural instability 🔸 Other features: • Masked (expressionless) face • Shuffling gait with reduced arm swing • Micrographia, hypophonia 🧩 Pathology: Degeneration of Substantia Nigra → ↓ Dopamine 🧬 Genetics: Usually sporadic. Rare familial forms → SNCA, PARK2 ⸻ 2️⃣ Huntington’s Disease 🔸 The triad: CHOREA + COGNITION + PSYCHIATRIC • Chorea → involuntary jerky, dance-like movements • Dementia → personality changes, cognitive decline • Psychiatric → depression, psychosis, impulsivity 🔸 Onset: Typically 30–50 years old • Younger onset = more severe (anticipation!) 🧩 Pathology: Degeneration of Caudate Nucleus → loss of GABA neurons 🧬 Genetics: Autosomal Dominant — CAG trinucleotide repeat expansion on chromosome 4 ⸻ 3️⃣ Head-to-Head Comparison ➊ Movement type • Parkinson’s → TOO LITTLE movement (hypokinesia) • Huntington’s → TOO MUCH movement (hyperkinesia) ➋ Pathology • Parkinson’s → Substantia Nigra (↓ Dopamine) • Huntington’s → Caudate Nucleus (↓ GABA) ➌ Genetics • Parkinson’s → mostly sporadic • Huntington’s → always autosomal dominant, 100% penetrance ➍ Treatment • Parkinson’s → Levodopa/Carbidopa (replace dopamine) • Huntington’s → Tetrabenazine for chorea (no disease-modifying therapy) ⸻ ⚠️ Exam Pearl 🔹 Huntington’s shows ANTICIPATION — each generation presents earlier and more severely 🔹 If you see choreiform movements + psychiatric symptoms in a young adult → think Huntington’s first ⸻ 📚 Master movement disorders and all of neurology in our high-yield neurology book: 🔗 www.mediconotes.com ⸻ #Parkinsons #Huntingtons #Neurology #MovementDisorders #MedicalEducation

Understanding the Monro-Kellie Doctrine The Monro-Kellie Doctrine is a principle that describes the fixed volume relationship among the components within the cranial cavity. These components include brain tissue, blood, and cerebrospinal fluid (CSF). It helps explain how changes in the volume of one component can affect the others and the overall intracranial pressure (ICP). Components: Brain Tissue: Represents about 80% of the cranial cavity volume. Blood: Accounts for approximately 10% of the volume. Cerebrospinal Fluid (CSF): Makes up the remaining 10%. The Doctrine's Principle: Fixed Volume: The total volume within the cranial cavity is fixed because the skull is rigid and non-expandable. Compensation Mechanism: An increase in the volume of one component (e.g., brain tissue due to oedema, blood due to haemorrhage, or CSF due to hydrocephalus) must be compensated by a decrease in the volume of another component to maintain a stable ICP. Compensatory Mechanisms: CSF Shifts: CSF can be displaced into the spinal subarachnoid space. Blood Volume Changes: Venous blood can be displaced from the intracranial compartment. Brain Tissue Compliance: Limited capacity to accommodate changes due to its relatively inelastic nature. #nursingclinicals #pathophysiologyexam #pathophysiologyclass #pathophysiologynotes #nursingstudentsofinstagram #nursingstudentnotes #studentnurses #futurenurses #nursingresources #nurseintraining #nurseinprogress #nursetobe #nursingassociates #traineenursingassociates #traineenursingassociate #studentnursestruggles #studentparamedicuk #studentparamedicsuk #studynursing #studentnurseuk #studentnurse #nursingnotes #nursingschool #nursingstudent #studentnursesofinstagram #studentparamedic #pathophysiology

The Babinski Reflex 🦶 Also known as the plantar reflex is evoked when pressure is applied to the lateral aspect of the sole of the the foot, running from the heel to the toes across to the big toe. A normal or absent Babinski occurs when the toes go downward (plantar flexion) A abnormal or positive Babinski occurs with dorsiflexion of the big toe, with the other toes fanning out. While abnormal in adults this is a normal finding in infants through the age of two. A positive Babinski is associated with central nervous system 🧠disorders such as spinal cord trauma, spinal cord tumor, multiple sclerosis, amyotrophic lateral sclerosis and stroke
