44 Male, very athletic, physically fit and active. Diagnosed with enlarged heart (idiopathic cardiomyopathy) 3 years ago. EF ratio of 50. Diagnosed 5 years ago with essential tremor as well. I understand essential tremor worsens over time and my symptoms are very strange. Fatigue, aggression, mood swings, tremors in hands arms and can be any body part. Muscle cramping all over body (was bad for about a week and has subsided) happens a couple times during the week. Tremors are worse at rest. My cognitive test today was normal/average however I know that my performance was sub-par based on cognitive deterioration over the past year. I cannot sit still, feel like I tense up and need to wiggle around (only good way to describe). Running blood test and trying to schedule MRI. Thoughts and or suggestions?
