Actor Michael Wright, best known for playing Eddie King Jr. in the 1991 musical drama The Five Heartbeats, has died at the age of 70 in Los Angeles. According to his kin, Wright died on August 19. His death was linked to heart failure along with complications from Marchiafava-Bignami disease, a rare degenerative neurological condition. His wife, Susan Wright, announced his death in a social media post, “It is with profound sadness and an unimaginable heaviness in my heart that I share the passing of my beloved husband, Michael Wright,” Susan wrote, remembering the actor as a “loved one, a friend, and an extraordinary artist whose work touched generations.”Wright’s Died Due To Marchiafava-Bignami DiseaseAlso read: Two-Decade Long Study Sees 50% Higher Risk Of Distal Colon Cancer In Men With High Dietary Nitrite IntakeAccording to a statement from Wright’s family, he suffered heart failure together with complications from Marchiafava-Bignami disease. MBD is a rare neurological disorder that primarily affects the corpus callosum, the thick bundle of nerve fibres connecting the brain’s two hemispheres. It is most commonly associated with severe alcohol use disorder and nutritional deficiencies, although it can occur in other circumstances.The condition can cause symptoms including confusion, impaired consciousness, problems with movement, seizures and changes in cognitive function. As MBD is extremely rare, doctors may have difficulty recognising it, particularly in its early stages.Wright's cause of death was heart failure due to the neurological disease. Heart failure occurs when the heart cannot pump enough blood to meet the body's needs. Depending on the type and severity, this can lead to breathlessness, fatigue, swelling in the legs, rapid heartbeat and reduced ability to perform everyday activities.Heart failure can develop because of conditions including coronary artery disease, high blood pressure, heart attacks, cardiomyopathy and abnormal heart rhythms. In Wright's case, his family said heart failure occurred alongside complications from MBD. They did not publicly provide further details about what caused his heart failure.Also read: How Genetic and Genomic Testing Can Help Women Make Smarter Cancer DecisionsWright Had A Career Spanning Nearly Five DecadesMichael Wright began his acting career in the late 1970s, making his screen debut in The Wanderers in 1979.
