Summary:

- The article discusses a study that found abnormal blood vessel growth in the brains of people with Alzheimer's disease.
- Researchers used a new imaging technique to visualize the blood vessels in the brains of Alzheimer's patients and found that the blood vessels were disorganized and leaky, which could contribute to the cognitive decline seen in the disease.
- The findings suggest that targeting the abnormal blood vessel growth in the brain could be a potential new therapeutic approach for treating Alzheimer's disease.
