An aldosterone-producing adenoma (APA) is a small, benign (non-cancer) tumor in one adrenal gland that makes too much aldosterone. Aldosterone is a hormone that tells the kidneys to hold on to salt and water and to let go of potassium. When aldosterone is too high, the body keeps extra salt and water, blood pressure goes up, and potassium often goes down.
Very low potassium and very high blood pressure can affect the brain and nerves. This can lead to seizures and other neurological problems such as confusion, headaches, weakness, tingling, vision changes, and trouble thinking. In short: the tumor causes hormone imbalance; the imbalance drives high blood pressure and low potassium; those changes can trigger seizures and nerve/brain symptoms.
Why seizures and neurological problems happen
Low potassium (hypokalemia): Nerve and muscle cells use potassium to send signals. If potassium falls too low, brain and muscle cells misfire. This can cause muscle cramps, weakness, and seizures.
Very high blood pressure: Sudden or severe spikes can damage small brain vessels or cause brain swelling (hypertensive emergency). This can trigger headaches, confusion, vision loss, and seizures.
Alkalosis (blood too “alkaline”): Excess aldosterone often causes loss of hydrogen ions and chloride, raising blood bicarbonate. This “metabolic alkalosis” also disturbs nerve excitability and can encourage seizures or tingling.
Magnesium shifts: Low potassium often comes with low magnesium, which can lower the seizure threshold.
Brain complications of hypertension: Long-standing high blood pressure can lead to small strokes, posterior reversible encephalopathy syndrome (PRES), or hypertensive encephalopathy, all of which can cause seizures and neurological symptoms.
Other names
Conn syndrome (classic name for aldosterone excess from an adrenal adenoma)
Unilateral primary aldosteronism (because it usually affects one adrenal)
Aldosterone-secreting adrenal adenoma
APA (short form used in medical notes)
Sometimes simply grouped under primary aldosteronism (PA), which also includes other causes besides adenoma.
Types
By side:
Unilateral APA (most common): the adenoma is in one adrenal gland.
Bilateral disease exists in primary aldosteronism but is usually due to hyperplasia, not adenoma; still helpful when comparing tests and treatment choices.
By potassium level:
Hypokalemic APA: low potassium is present; seizures and muscle symptoms are more likely.
Normokalemic APA: potassium appears normal; aldosterone is still high and blood pressure can still be resistant.
By blood pressure pattern:
Severely elevated or labile blood pressure (higher risk of neurologic events).
Moderately elevated but resistant to medicines.
By genetic/molecular features of the tumor (found in the tumor tissue):
KCNJ5 mutation, ATP1A1, CACNA1D, ATP2B3, etc. These affect how adrenal cells handle ions and calcium, which drives aldosterone overproduction.
By imaging/vein sampling result:
Clearly lateralized (one side is the source) vs. uncertain (needs adrenal venous sampling to confirm).
By clinical presentation:
Neurologic-dominant presentation (seizures, confusion, vision change).
Cardiovascular-dominant presentation (resistant hypertension, palpitations).
Mixed features.
Causes
These include causes of the hormone problem itself (the tumor and biology behind it) and causes/triggers that make seizures or neurologic problems more likely in a person who already has APA.
Benign adrenal tumor (adenoma): The core cause—an overactive cluster of adrenal cells forms a small tumor that makes aldosterone without normal control.
Somatic gene mutations in tumor cells (e.g., KCNJ5): These changes alter cell channels and calcium signaling, pushing the cell to make aldosterone continuously.
Chronic sodium retention: Extra salt and water raise blood pressure, increasing brain and vessel stress.
Renin suppression: High aldosterone shuts down renin; this locks the body into an aldosterone-driven state with ongoing hypertension.
Hypokalemia (low potassium): Potassium loss via kidneys leads to nerve and muscle hyper-excitability or failure, which can cause seizures and weakness.
Metabolic alkalosis: Loss of hydrogen ions increases blood alkalinity; this promotes neuromuscular irritability and seizures.
Hypomagnesemia: Magnesium helps stabilize nerve firing; low magnesium lowers the seizure threshold.
Hypertensive encephalopathy: Sudden, severe blood pressure rises can cause brain swelling and seizures.
Posterior reversible encephalopathy syndrome (PRES): Severe hypertension and endothelial injury can cause headaches, vision loss, and seizures.
Small vessel disease or microbleeds from hypertension: Long-term high pressure injures brain microvessels, raising stroke and seizure risk.
Ischemic or hemorrhagic stroke: Either type can occur with uncontrolled hypertension and can present with seizures.
Dehydration or diuretic overuse: Can worsen potassium loss and trigger seizures.
High salt intake: Feeds the aldosterone effect, further elevating blood pressure and potassium loss.
Licorice or glycyrrhizin consumption: Acts like a mineralocorticoid, magnifying aldosterone effects and potassium loss.
Certain medications: Loop/thiazide diuretics (increase potassium loss), high-dose beta-agonists, or amphotericin B can worsen hypokalemia and neurologic risk.
Vomiting or diarrhea: Extra potassium and fluid loss lower potassium and raise alkalosis.
Kidney impairment: Reduces the body’s ability to balance potassium and acid–base status, intensifying symptoms.
Sleep apnea with resistant hypertension: Common in primary aldosteronism; nocturnal surges in BP can contribute to neurologic events.
Stress and sleep deprivation: Lower seizure threshold in susceptible people; also worsen BP control.
Alcohol excess or stimulant use: Can provoke seizures and spike blood pressure, adding to the risk from APA.
Symptoms
High blood pressure that is hard to control, sometimes with headaches or nosebleeds.
Headaches, often throbbing or pressure-like, linked to blood pressure spikes.
Muscle weakness, heaviness, or fatigue due to low potassium.
Muscle cramps or spasms, especially in the legs and hands.
Tingling or numbness around the mouth, fingers, or toes (nerve irritability from alkalosis or low potassium).
Palpitations or a feeling of skipped heartbeats (arrhythmias are more likely with hypokalemia).
Increased urination (polyuria) and night urination (nocturia) from salt and water handling changes.
Extreme thirst, often linked with frequent urination.
Fatigue, low energy, and reduced exercise tolerance.
Mood or cognitive changes such as irritability, poor concentration, or slowed thinking.
Dizziness or light-headedness, especially with posture changes or during BP swings.
Vision changes, such as blurry vision or temporary vision loss during severe BP spikes (possible PRES).
Seizures, which can be focal or generalized; sometimes the first alarming sign.
Confusion or altered awareness during hypertensive emergencies or strokes.
Stroke symptoms such as weakness on one side, trouble speaking, or facial droop (not in every patient, but possible when BP is uncontrolled).
Diagnostic tests
(Grouped as requested. Each item explains what the test is and why it helps.)
A) Physical exam
Repeated blood pressure measurements (sitting and standing): Doctors measure BP several times to confirm persistent hypertension and to see patterns. Very high or fluctuating readings suggest a secondary cause like aldosterone excess.
General neurological exam: Checks alertness, memory, speech, cranial nerves, coordination, strength, and sensation. It helps detect complications such as focal deficits, encephalopathy, or post-ictal changes after a seizure.
Muscle strength and reflex testing: Low potassium can cause weakness and reduced reflexes; sometimes reflexes become brisk if there is central nervous system involvement from high BP.
Fundoscopic (eye) exam: Looking at the retina for hypertensive changes (narrowed vessels, hemorrhages, cotton-wool spots, swelling of the optic disc). These signs support severe or long-standing hypertension that may explain neurologic symptoms.
B) Manual/bedside tests
Orthostatic vital signs: BP and heart rate measured lying, sitting, and standing. This shows volume status and autonomic effects. In APA, volume expansion can blunt normal standing responses.
Confrontation visual field testing: A simple bedside check for visual field loss. Helpful if the patient reports vision problems that could suggest PRES or stroke.
Bedside mental status testing (e.g., MMSE or MoCA): Quick paper-and-pencil tests of attention, memory, and language. Useful to document cognitive changes from hypertensive encephalopathy or recurrent seizures.
C) Lab and pathological tests
Serum electrolytes (potassium, sodium, bicarbonate, magnesium): In APA, potassium is often low, bicarbonate is high (metabolic alkalosis), sodium may be slightly high, and magnesium can be low—findings that explain cramps and seizures.
Plasma aldosterone concentration (PAC): Usually elevated in APA. High PAC is a key clue that the adrenal is producing excess aldosterone.
Renin (plasma renin activity or direct renin concentration): Typically suppressed in primary aldosteronism. Low renin together with high aldosterone is the classic biochemical fingerprint.
Aldosterone–renin ratio (ARR): A calculated screening index. A high ARR strongly suggests primary aldosteronism and points toward APA when imaging later shows a nodule.
Saline infusion test (confirmatory): IV saline is given; in healthy people, aldosterone should drop. If aldosterone stays high, that confirms autonomous secretion.
Oral sodium loading test with 24-hour urine aldosterone: High salt intake for several days; if urinary aldosterone remains high, it confirms the diagnosis.
Tumor histopathology with CYP11B2 staining (after surgery): The removed nodule is examined under a microscope and stained for aldosterone-making enzyme (CYP11B2) to prove it is truly an aldosterone-producing adenoma.
D) Electrodiagnostic tests
Electroencephalogram (EEG): Records brain electrical activity. It confirms seizures, classifies seizure type, and tracks changes after correcting potassium and blood pressure.
Electrocardiogram (ECG): Looks for arrhythmias and classic hypokalemia changes (like U-waves, ST-segment changes). This helps explain palpitations and guides safe potassium repletion.
Nerve conduction studies/EMG (selected cases): If weakness persists, these tests look for a hypokalemic myopathy or neuropathy pattern.
E) Imaging tests
Adrenal CT (or MRI): Searches for an adrenal nodule on one side. A small, well-defined nodule supports APA. CT also rules out rare cancer features.
Adrenal venous sampling (AVS): A targeted catheter test that measures aldosterone from each adrenal vein. It proves which side is over-secreting. This is often needed before surgery, especially in adults over ~35 or when CT is unclear.
Brain MRI (or CT) when neurologic signs are present: Rules out stroke, brain bleeding, and PRES. It explains seizures or visual symptoms and guides urgent care if needed.
Treatment roadmap
Stabilize emergencies first: treat seizures, correct low potassium and magnesium, and control very high blood pressure safely.
Confirm the diagnosis: blood tests, salt/medicine tests, CT scan, and often adrenal vein sampling to be sure the tumor is on one side.
Definitive treatment: laparoscopic adrenalectomy (minimally invasive surgery) if the tumor is unilateral.
Medical control when surgery isn’t suitable: mineralocorticoid receptor blockers (spironolactone or eplerenone), plus other blood-pressure medicines as needed, plus potassium and magnesium correction.
Follow-up: watch blood pressure, potassium, kidney function, and any neurological symptoms.
Safety note: Dosages below are typical adult doses. Your clinician adjusts these to your health, kidneys, other medicines, and pregnancy status.

Regenerative / Stem-Cell” Drugs — Important Note
For APA, there is no proven role for “stem-cell drugs” or immune-booster medicines. Using them can be harmful or wasteful. The best, evidence-based “regeneration” is correcting the hormone excess, normalizing potassium, controlling BP, and removing the tumor when appropriate.
Instead, here are safer, evidence-supported measures often mislabeled as “immune boosting,” with practical dosing where relevant:
Annual influenza vaccine — standard adult dose per guidelines.
Function: Prevents flu complications that can destabilize BP/electrolytes.
Mechanism: Immune priming against circulating strains.
Pneumococcal vaccine (per age/condition schedule).
Function: Prevents severe pneumonia/sepsis that can worsen BP control.
Mechanism: Antibody-mediated protection.
COVID-19 booster (as locally recommended).
Function: Reduces severe illness risk and hospital triggers for crises.
Mechanism: Adaptive immunity to variants.
Vitamin D optimization (see above dosing).
Function: Supports immune regulation and muscle function.
Mechanism: Nuclear receptor signaling.
Omega-3 (EPA/DHA) (see above).
Function: Anti-inflammatory vascular support.
Mechanism: Eicosanoid modulation.
Lifestyle “immune supports”: sleep 7–9 h, exercise, stress care, balanced diet.
Function: Lowers stress hormones and improves immune competence.
Mechanism: Neuro-endocrine balance.
If you see clinics offering “stem-cell” therapy for APA, that is not standard care. Avoid unless in a regulated clinical trial approved by your medical team.
Surgeries/Procedures
Laparoscopic transperitoneal adrenalectomy (unilateral)
Procedure: Keyhole surgery through the abdomen to remove the adrenal with the adenoma.
Why: Definitive cure for unilateral APA; normalizes aldosterone and improves or cures hypertension and low potassium.
Posterior retroperitoneoscopic adrenalectomy
Procedure: Keyhole surgery through the back/flank without entering the peritoneal cavity.
Why: Faster recovery, less pain for some; choice depends on surgeon/anatomy.
Partial (cortical-sparing) adrenalectomy
Procedure: Removes only the tumor, leaves some adrenal tissue.
Why: Rarely chosen for APA; may be considered to preserve adrenal function in select cases.
Thermal ablation (radiofrequency or microwave) — selected non-surgical candidates
Procedure: Needle energy destroys adenoma tissue under imaging guidance.
Why: For patients unfit for surgery; evidence is smaller than for surgery.
Adrenal artery embolization (selected/experimental)
Procedure: Catheter blocks blood flow to the adenoma.
Why: Option when surgery is not feasible and expertise is available; outcomes vary.
After surgery, potassium often normalizes quickly. Blood pressure may take weeks to months to fully improve.
Preventions
You cannot always prevent a tumor, but you can lower risks and avoid crises.
Control sodium intake.
Keep a steady intake of potassium-rich foods only as advised with your meds.
Maintain healthy weight and regular exercise.
Don’t smoke; limit alcohol and caffeine.
Treat sleep apnea.
Avoid black licorice/glycyrrhizin products.
Minimize routine NSAID use; ask your doctor for safer pain options.
Regular home BP checks and lab monitoring plan.
Medication list review with your doctor (diuretics, steroids, decongestants can affect BP/K+).
Family awareness and early screening for resistant hypertension.
When to see a doctor
Immediately/ER: seizure lasting >5 minutes, repeated seizures, severe chest pain, sudden weakness or paralysis, confusion, fainting, BP ≥180/120 mmHg with symptoms (headache, vision loss, chest pain, shortness of breath), or severe muscle weakness.
Urgent appointment: new or worsening headaches, palpitations, muscle cramps, tingling, swelling, very low energy, home BP consistently above your target, or potassium/magnesium results out of range.
Routine: follow the testing and visit schedule your clinician sets (especially right after diagnosis and after surgery or med changes).
What to eat and what to avoid
Eat: fresh vegetables and fruits (doctor-guided potassium).
Eat: whole grains, legumes, nuts, and seeds for magnesium and fiber.
Eat: lean proteins (fish, poultry, tofu, beans).
Eat: healthy fats (olive oil, omega-3 fish).
Limit: salt to <2 g/day sodium; avoid processed/packaged foods.
Avoid: black licorice/herbals with glycyrrhizin.
Limit: alcohol and energy drinks.
Be careful: potassium salt substitutes if you take spironolactone/eplerenone or have kidney disease—ask your doctor first.
Hydrate: regular water intake; avoid extreme dehydration.
Watch: caffeine—keep to modest amounts if it spikes your BP.
Frequently Asked Questions
Is APA cancer?
No. It is a benign tumor that makes too much aldosterone.Why do seizures happen with APA?
Usually from very low potassium or dangerously high BP irritating the brain. Fixing electrolytes and BP lowers seizure risk.Is surgery a cure?
For unilateral APA, yes—often. Many patients see normal potassium and improved or normal blood pressure after adrenalectomy.Will I still need BP pills after surgery?
Some do, especially if they had high BP for many years, are older, or have stiff arteries. But doses are usually lower.What if I cannot have surgery?
Spironolactone or eplerenone control the disease well for many people; other BP drugs are added as needed.Do I always need adrenal vein sampling (AVS)?
Often yes in adults, to prove the extra hormone comes from one side. It guides whether surgery will help.Can I use potassium salt instead of table salt?
Only if your doctor says it’s safe. On MR blockers or with kidney issues, potassium salt can cause high potassium.Is this the same as bilateral adrenal hyperplasia?
No. APA is a tumor on one side; bilateral hyperplasia is both glands overactive. Treatment choices differ.Will seizures come back?
If potassium and BP stay stable, seizures are much less likely. Follow your plan and neurology advice.Can I get pregnant with APA?
Discuss early with your team. Some BP drugs (ACEI/ARB, spironolactone) are not safe in pregnancy; eplerenone may be considered case-by-case. Surgery might be planned before pregnancy.Does licorice really matter?
Yes. Black licorice and glycyrrhizin can mimic aldosterone and worsen BP/potassium.What’s my BP goal?
Common targets are <130/80 mmHg, but your clinician personalizes this to you.How fast will potassium normalize?
Often within days with replacement and MR blockade; after surgery, it may normalize very quickly.Could APA come back?
After removing the affected gland, recurrence is rare. You still need routine health checks.Are stem-cell or “immune-boost” therapies helpful?
No. They’re not proven for APA and may be unsafe. Stick to evidence-based surgery/medicines and lifestyle care.
