Shah, MD.Jan 31, 2017
Does essential tremor get worse over time? Typically, ET symptoms gradually worsen over time. While most people with ET only experience mild to moderate symptoms as they age, others may experience substantial disability.
During the past decades the diagnostic criteria have been refined and ET was first contrasted against other tremor entities in the Movement Disorder Society 1998 tremor classifi- cation [6] which was recently updated in 2017 [7]. Marsden stated in 1983 that 'essential tremor is not a single entity' [5].Sep 1, 2017

Be reassured that worsening of tremor after exercise is expected due to the increase of adrenaline (or epinephrine and norepinephrine) during exercise. Adrenaline, released during any physical or psychological stress, leads to increased muscle activity manifested as worsening of tremor.
The tremor may worsen over time and may spread to parts of the body not pre- viously affected.

Studies have shown different rates of essential tremor. Some have shown it to be present in 1 in 250 people. However, other studies have shown it may affect as many as 1 in 17 people. It is equally common in men and women and is more common with increasing age.
Genes are passed on to a child from each parent and determine what we look like, how our body functions and even what diseases we get. Particular genes have been shown to have certain changes present in families with essential tremor. It is not clearly understood how this genetic change leads to essential tremor.
There are two main medicines used initially for essential tremor - propranolol and primidone. These medicines have been shown to ease the tremor in about half of affected people. Propranolol is a medicine that is usually used in heart disease. It is in a class of medicines called beta-blockers.
Essential tremor cannot be cured. Treatment reduces the severity of the tremor, sometimes greatly. There are various treatments that are used. Some people only take medication when they are in situations in which their tremor worsens. For example, if they are giving a presentation or going to a job interview.
If medicine treatment is not effective and the tremor is severe, a surgical procedure may be an option.

The onset of familial ET is usually during childhood, whereas sporadic ET usually occurs in those over 40 years of age.
If action tremor worsens as goal-directed movement approaches its intended target, this is intention tremor (indicative of a cerebellar cause). Associated with brainstem or cerebellar disease, including multiple sclerosis, spinocerebellar degenerations, vascular disease and tumours.
Mental stress or general movement makes rest tremors worse. Action tremors are further subdivided into static, postural or kinetic tremors: Static - occurs in a relaxed limb when fully supported at rest. Causes include Parkinson's disease, Parkinsonism, other extrapyramidal diseases and multiple sclerosis.

ET is generally considered to be a neurodegenerative disease . Factors predicting likely progression include asymmetric tremor, unilateral onset of the initial tremor and age of onset. If the tremor occurs before the age of 40 years then the rate of progression is low.
Can occur in a state of normality or in an exaggerated form, due to a precipitant such as anxiety, hyperthyroidism, hypoglycaemia, caffeine excess, fever, medication, etc. It is usually associated with certain postures. It is usually bilateral, symmetrical and non-progressive over time.
Receiving optimal benefit from botulinum toxin requires a specialist skilled in the technique. The effects last about three to four months and, for continued benefit, must be repeated about three times a year. Transient weakness of the injected muscles is the most common side effect. Be sure to check with your insurance provider about coverage, as this treatment can be expensive.
Due to its lack of effectiveness for the majority of persons with ET and its significant side effects, mirtazapine is not recommended for the routine treatment of ET. Adverse effects include sleepiness, increased appetite/weight gain, dizziness and nausea.
Propranolol is currently the only medication approved by the Food and Drug Administration (FDA) for the treatment of ET. Propranolol is in a class of drugs called beta-blockers, which are used primarily for treating high blood pressure. These drugs block adrenaline in the nervous system; however, it is not clear exactly how propranolol works in treating ET.
