It's looking like MS strikes when a variety of triggers gang up to impair neurons in the brain and spinal cord. Researchers are using their new knowledge to search for treatments.
Research suggests the winter blues are triggered by specialized light-sensing cells in the retina that communicate directly with brain areas involved in mood.
People with symptoms suggesting depression felt better immediately when tiny pulses of electricity reached a brain area called the lateral orbitofrontal cortex.
