Unraveling the Impact of Methamphetamine

Methamphetamine addiction is a serious problem that can harm both the brain and heart. This drug triggers a strong high by releasing dopamine, which is linked to feelings of pleasure and reward. Long-term use of methamphetamine can reduce the function and integrity of dopamine receptors in the brain, leading to habituation, escalating use and dependence.

Moreover, methamphetamine addiction can cause neuoinflammation in neural and cardiac tissue. This can lead to cognitive changes, particularly in executive functioning, attention and working memory. Cardiac inflammation can lead to heart disease, pulmonary hypertensions, congestive heart failure, and even sudden death.

We are pioneering the use of Magnetic Resonance Imaging (MRI) to quantify changes in cardiac and neural structure and function caused by harmful methamphetamine use. This study uses a variety of innovative imaging methods and computer-based cognitive testing to measure cognitive function or how well the brain is working. Our goal is to improve understanding of the impact of harmful Methamphetamine use as well as recovery following abstinence, providing crucial insights for methamphetamine addiction treatment services.
