Quick Answer
After 40, regular health screening catches problems early — but not every test is necessary. Here's an evidence-based checklist for adults over 40.

After age 40, the risk of chronic diseases — hypertension, diabetes, heart disease, cancer and neurological conditions — begins to rise. Regular health screening can detect problems early when they're most treatable. But not every test is necessary, and screening too frequently or testing for everything wastes money and can cause harm through false positives.
Core screenings everyone over 40 should have
- Blood pressure: at least annually — hypertension is the leading modifiable stroke risk.
- Blood sugar/HbA1c: every 1–3 years depending on risk factors.
- Lipid profile (cholesterol): every 1–5 years depending on risk.
- Cancer screening: colorectal cancer screening (colonoscopy or stool test), breast cancer screening for women, cervical cancer screening.
- Eye exam: annually after 40 — catches glaucoma, cataracts, diabetes-related eye disease.
- Dental exam: every 6 months — gum disease linked to cardiovascular disease.
Neurological screenings worth considering
- Cognitive screening: brief cognitive tests (MoCA) if you or family notice memory changes.
- Hearing test: audiogram if you notice hearing difficulty.
- Bone density (DEXA): for women over 65, men over 70, or earlier with risk factors.
- Depression screening: annual — mood disorders are common and treatable.
Tests that are NOT routinely recommended
- Full-body CT scans: high radiation, low benefit for asymptomatic people.
- Tumor marker blood tests: not recommended for general screening.
- Whole-body MRI: expensive, low yield, often finds incidental findings that cause anxiety.
- Routine ECG for low-risk people: not recommended without symptoms or risk factors.
How often to get checked
Most annual physicals include blood pressure, weight, basic labs and a physical exam. More detailed screening (lipids, diabetes, cancer screening) follows evidence-based intervals. Keep a personal health record of your results and share them with all your doctors. At Kathmandu Neurology Clinic, we review your overall health picture — not just neurological symptoms — because vascular risk factors directly affect brain health.
When to seek professional evaluation
Health screening is personalized based on your age, family history, risk factors and symptoms — discuss your screening schedule at your next checkup.

Note time of onset, call emergency services, do not give food/drink or leave the person alone.
TIA symptoms resolve, but it signals high short-term stroke risk. Urgent evaluation and prevention planning are essential.
Early discussion is helpful when concerns affect daily life; screening approach is individualized.
No; occasional lapses, stress-related memory changes, and other conditions can affect memory. Persistent functional impact warrants evaluation.
