Introduction

Scientists in Hong Kong made a new nose spray. It helps the brain after a stroke.

Main Body

Many people have strokes. Most medicines do not reach the brain because the brain has a strong wall. This wall stops the medicine. Many patients arrive at the hospital too late. Scientists made a new 'Nanopowder' spray. The medicine goes through the nose and straight to the brain. It goes around the brain wall. This spray works fast. If a person uses it in 30 minutes, it saves 80 percent of the brain. It helps the person move and think better. Now, people can get help before they reach the hospital. This is better than waiting for a doctor to remove a blood clot.

Conclusion

The Nanopowder spray can stop brain damage and help stroke patients.
