A human model of the blood-brain barrier
Disruptions to the protective barrier contribute to the development of serious brain diseases such as stroke and Alzheimer's.

stroke
In a stroke, the brain or parts of it are no longer supplied with sufficient blood, which impairs the supply of oxygen and glucose. The most common cause is a blockage in an artery (ischemic stroke), less commonly a hemorrhage (hemorrhagic stroke). Typical symptoms include sudden visual disturbances, dizziness, paralysis, speech or sensory disturbances. Long-term consequences can include various sensory, motor, and cognitive impairments.

Apraxia
Difficulty performing a purposeful movement, such as grasping a glass or cutting with scissors. Depending on the form of apraxia, speech or facial expressions may also be affected. The cause is not muscle weakness or paralysis, but damage to one or more areas of the brain, e.g., as a result of a stroke. In other cases, however, it is congenital.

diffusion tensor imaging
Diffusion tensor imaging (DTI) is a form of magnetic resonance imaging. It enables researchers and physicians to visualize how water distributes itself in space over time, allowing them to reconstruct nerve pathways in the brain, for example. Certain changes, such as those caused by a stroke, can be detected more effectively with diffusion tensor imaging than with conventional magnetic resonance imaging.
