NFL legend Brett Favre shared an update on his Parkinson's disease battle, a year after his diagnosis. Favre, who has idiopathic Parkinson's, the most common form, discussed his symptoms on his podcast. He noted that shaking is not his primary symptom, but he experiences significant rigidity and stiffness, particularly in the mornings before medication. While fatigue can cause minor tremors later in the day, his cognitive and memory functions have remained stable so far.
