What Systolic Blood Pressure Means for Long-Term Brain Health
Blood pressure is measured with two numbers, and the top number is called systolic pressure.
Dr Kota Reddy said readings of 100 or 110 can be good for the brain if they do not cause dizziness.
He also said the top number should ideally stay below 120.
High blood pressure can hurt the brain over time.
This warning applies to people of any age.
Dr Nitin K Sethi agreed that healthy blood pressure can lower the risk of strokes and damage to tiny blood vessels in the brain.
However, he said blood pressure that is too low can also cause problems.
So the goal is a healthy range, not simply the lowest possible number.
Dr Kota Reddy said systolic blood pressure of 100 or 110 mmHg may be best for the brain when it causes no dizziness.
He advised keeping systolic blood pressure below 120 mmHg to help protect brain health.
Reddy said high blood pressure can harm the brain regardless of a person’s age.
Dr Nitin K Sethi said healthy blood pressure can reduce long-term stroke and small-vessel brain damage risks.
Sethi cautioned that excessively low blood pressure can also cause problems, so lower is not always better.
- Who
- Cardiologist Dr Kota Reddy and neurosciences specialist Dr Nitin K Sethi discussed blood pressure and brain health.
- What
- They explained how systolic blood pressure levels may affect the brain, including the risks of high and excessively low readings.
- When
- Recently, during Dr Kota Reddy’s discussion with fitness expert Terri Alani.
- Where
- The discussion was conducted with Terri Alani; Dr Nitin K Sethi is associated with PSRI Hospital.
- Why
- To explain how maintaining blood pressure in a healthy range may help protect the brain and reduce long-term health risks.
Lower Systolic Pressure Emphasis
Healthy-Range Caution
How low should pressure be?
Lower Systolic Pressure Emphasis
Dr Kota Reddy said systolic readings of 100 or 110 mmHg may be best for the brain when they do not cause dizziness, and recommended staying below 120 mmHg.
Healthy-Range Caution
Dr Nitin K Sethi said lower blood pressure is not automatically better because excessively low pressure can also cause problems.
Managing brain-health risk
Lower Systolic Pressure Emphasis
Reddy emphasized that high blood pressure can hurt the brain and that age does not remove this risk.
Healthy-Range Caution
Sethi emphasized balance: blood pressure in a healthy range may reduce stroke and small-vessel damage risks, while pressure that is too low may be harmful.
- Systolic pressure
- The upper number in a blood pressure reading.
- Reading cited as potentially best
- A systolic reading of 100 or 110 mmHg, provided it does not cause dizziness.
- Suggested upper target
- Dr Kota Reddy said systolic blood pressure should ideally remain below 120 mmHg for brain protection.
- High blood pressure
- Reddy said high blood pressure can harm the brain regardless of age.
- Stroke risk
- Healthy blood pressure can reduce long-term stroke risk, according to Dr Nitin K Sethi.
- Small-vessel damage
- Healthy blood pressure may reduce the risk of damage to the brain’s small blood vessels.
- Important caution
- Excessively low blood pressure can also cause problems.
