Introduction to MCAS

In this presentation at the 2021 LDN Conference, Dr. Leonard Weinstock provides an overview of Mast Cell Activation Syndrome (MCAS). He describes mast cells as large cells originating in the bone marrow, which play a crucial role in healing and immune response. MCAS results from both genetic/epigenetic factors and environmental influences, leading to a systemic condition with varied symptoms. Common symptoms include fatigue, brain fog, panic attacks, gut issues, heart palpitations, and skin manifestations like hives and itching. Dr. Weinstock emphasizes that MCAS is interconnected with neuropsychiatric and cardiovascular phenomena, illustrating its systemic impact.
