Essential tremor is a type of uncontrollable shake or tremble of part of the body.  

It is a common movement disorder that for most people is a minor nuisance, however, it does get gradually worse with time. At its most severe, essential tremor is disabling and makes it very difficult to perform daily activities (see below).

Essential tremor usually affects the arms and hands, although it can also affect other body parts, including head, face, jaw, tongue and feet.

Sometimes, the voice can also sound shaky. Read more about symptoms of essential tremor.

There is no cure for essential tremor, but medicines can be used to help improve the symptoms in at least half of people with the condition. Read more about treatment of essential tremor.

'Normal' tremor

Everyone has a very minor tremor when carrying out daily activities. For example, your hands will shake slightly when you hold them out in front of you. This is normal.

Sometimes, the everyday level of tremor can become more noticeable, particularly in older people. Noticeable tremor is also normal and it is often caused by a raised level of adrenaline in the body, which can happen when a person is stressed, anxious or angry.

It can also occur when a person is taking certain types of medication, such as inhalers for asthma.

When does a tremor become a disorder?

Essential tremor is more severe than normal tremor. It can be made worse by the same things that cause normal tremor, such as stress and anxiety.

Essential tremor gradually gets worse over the years. Eventually, the tremor may become so severe that carrying out normal, everyday activities can become difficult. For example, activities such as writing, drinking a glass of water or tying shoelaces may become particularly challenging.

When to see your GP

It is important that you visit your GP if you experience frequent or severe tremors. They will carry out a physical examination to check for tremor when you move.

They will also ask about your medical history and that of your immediate family to find out whether essential tremor runs in your family.

There is no specific test to diagnose essential tremor. The condition is usually diagnosed after clinical assessment.

Who is affected?

Essential tremor affects men and women equally. It can affect people of any age, although it becomes more common with advancing age. Around 4 out of 100 adults over 40 years of age have the condition.

Essential tremor can run in families. At least half of people with the condition have a family member who also has it.

Why does there appear to be a lack of expertise and awareness in the uk regarding essential tremor disorder?why when ET is such a depilating and embarrassing condition which affects daily motor functions such as eating and writing are there no clinical trials such as effectiveness of exablate transcranial MR guided focused ultrasound for unilateral thalamotomy in the treatment of essential tremor in the uk. This can be a progressive condition which affects a great many people and is taken very seriously in america, spain, turkey, japan etc. why not in the uk or are we satisfied that the ongoing prescription of beta blockers is the answer to everything , which will be more expensive in the long term when one considers the continued lifetime prescription of drugs and the required costs of home care costs due to the patients inability to complete simple tasks such as dressing, writing and eating!! more awareness please and at least some interest shown by the NHS and or doctors/ surgeons for this condition. drugs are not the answer and prohibit in some cases the participation of people in the sports they love, further contributing to the isolation and cost of looking after the people with this condition.

Under "Who is affected", it reads "Around 4 out of 100 adults over 40 years of age are have the condition". This needs correcting. Sorry to be pedantic!
