Open Studies


Hypertension, Intracranial Pulsatility and Brain Amyloid-beta Clearance (HIPAC) Trial

Study Doctors: Rong Zhang, Ph.D., Wanpen Vongpatanasin, M.D., David Zhu, Ph.D., Ann Stowe, Ph.D.

Purpose of this study
  • Having high blood pressure (hypertension) in the middle and early-old age increases the risks of Alzheimer disease (AD) and other types of dementia later in life.
  • This study is to determine if lowering blood pressure with medication can reduce brain damage from high blood pressure and amyloid in the brain. Amyloid is a substance known to be high in the brain of older adults with dementia.

We will recruit 80 older adults with high blood pressure and 40 older adults with normal blood pressure for comparison

Do I qualify?

The participants should be 55-79 years old, with or without high blood pressure.

Should NOT have the following conditions:

  • History of stroke or other severe cerebrovascular disease
  • Clinical diagnosis of dementia or other neurodegenerative diseases, traumatic brain injury
  • Major or unstable heart disease, chronic kidney disease
  • Neurological and other severe medical conditions
  • History of drug or alcohol abuse within the last 2 years
  • Uncontrolled Diabetes (Hgb A1C >7.5%)

How will it work?

Compensate for time and effort.

Baseline visits:

After passing screening, you will visit our office 3 to 4 times to complete physical exam, blood draw, paper-and-pencil tests, ultrasound test, magnetic resonance imaging (MRI) and etc. With your permission, samples of cerebral spinal fluid (CSF) will be collected through a lumbar puncture.

Treatment:

We will provide you high blood pressure drugs to treat your high blood pressure if you have it. Your health condition will be monitored closely.

12-month follow-up visits:

If you have high blood pressure, we will repeat the tests as during baseline visits.
