action tremor  rhythmic, oscillatory, involuntary movements of the outstretched upper limb; it may also affect the voice and other parts.
coarse tremor  one in which the vibrations are slow.
essential tremor  a hereditary tremor with onset usually at about 50 years of age, beginning with a fine rapid tremor of the hands, followed by tremor of the head, tongue, limbs, and trunk.
fine tremor  one in which the vibrations are rapid.
flapping tremor  asterixis.
intention tremor  action t.
parkinsonian tremor  the resting tremor seen with parkinsonism, consisting of slow regular movements of the hands and sometimes the legs, neck, face, or jaw; it typically stops upon voluntary movement of the part and is intensified by stimuli such as cold, fatigue, and strong emotions.
physiologic tremor  a rapid tremor of extremely low amplitude found in the legs and sometimes the neck or face of normal individuals; it may become accentuated and visible under certain conditions.
pill-rolling tremor  a parkinsonian tremor of the hand consisting of flexion and extension of the fingers in connection with adduction and abduction of the thumb.
resting tremor  tremor occurring in a relaxed and supported limb or other bodily part; it is sometimes abnormal, as in parkinsonism.
senile tremor  that due to the infirmities of old age.
volitional tremor  action t.

1. An involuntary trembling movement.
2. Minute ocular movement occurring during fixation on an object.

Tremor
Shakiness or trembling.

tremor
[trem′ər, trē′mər]
Etymology: L, shaking
rhythmic, purposeless, quivering movements resulting from the involuntary alternating contraction and relaxation of opposing groups of skeletal muscles, occurring in some elderly individuals, certain families, and patients with various neurodegenerative disorders. Senile tremor is characterized by fine quick movements, especially of the hands, rhythmic head nodding, and increased trembling during purposeful movements. Familial tremor, which may be hereditary, and the tremor occurring in multiple sclerosis also increase during voluntary movement and may be intensified by anxiety, excitement, and self-consciousness. The tremors of Graves' disease, alcoholism, mercury poisoning, and other toxicoses are usually less rhythmic. The tremor in lead poisoning often affects the lips. The fine, quick, continuous tremor present in Parkinson's disease sometimes disappears during purposeful movements. Examples are resting tremor and intention tremor.

tremor (trem´r),
n rhythmic, purposeless, quivering movements resulting from the involuntary alternating contraction and relaxation of opposing skeletal muscle groups.

tremor
a continuous repetitive twitching of skeletal muscle, usually palpable and visible. The diseases characterized by tremor only, the tremor syndromes, may be caused by degenerative disease of the nervous system, e.g. hypomyelinogenesis, and by many toxins, especially plant ones. Tremor is also a sign in many other diseases of the nervous system.

action tremor
rhythmic, oscillatory, involuntary movements of the limbs.
coarse tremor
that involving large groups of muscle fibers contracting slowly.
congenital tremor syndrome of piglets
epidemic tremor
fibrillary tremor
rapidly alternating contraction of small bundles of muscle fibers.
fine tremor
one in which the vibrations are rapid.
intention tremor
one occurring when voluntary movement is attempted. See also volitional tremor (below).
rest tremor
tremor occurring in a relaxed and supported limb.
tremor syndrome
see shaker dogs. Called also white dog shaker syndrome.
volitional tremor
trembling of the entire body during voluntary effort.

tremor
Neurology Involuntary, rhythmic oscillations of a body part, commonly extremities, but also tongue, jaw, head, eyes, voice; tremors are a Sx and not a disease per se; they occur in primarily extrapyramidal, conditions–eg, advanced hepatic encephalopathy, Parkinson's disease, Wilson's disease, myoclonias Tremors as primary Sx Drug-induced tremor, essential tremor, familial tremor Management Beta-blockers–eg, propranolol, metoprolol, ethanol. Cf Drug-induced tremor, Essential tremor, Familial tremor, Flapping tremor, Intention tremor, Parkinson's disease, Vocal tremor.

Patient discussion about earth tremor.

Q. how do you know if you have early onset of alzheimers? i'm 47. i do have extreme tremors at times and memory l i was told this could be what i have by a psychiatrist. What else can cause me to have these symptoms at my age and how do i know?

A. Some early signs of Alzheimer's disease are:
Trouble remembering recent events.
Problems remembering namesof people and places.
Trouble solving simple math problems.

Alzheimer's disease usually affects people over 60. There are some illnesses and problems that may look like Alzheimer’s, but are caused by other problems.
These include:

Bad reaction to certain medicines
Depression
Not eating enough healthy foods, or too few vitamins and minerals in your body
Brain tumors
Blood vessel disease
Thyroid problems

Some of these illnesses can be treated. Once treated, your confusion and memory loss should go away. The point is to get checked out by your doctor. Don’t let fear stop you from seeing your doctor. You can get help.


Q. How do you tell between temporal shaky hands and parkinson disease? My dear granpa's hands are being a bit shaky lately. I was wondering if I should worry about Parkinson's disease or is it most likely to be something else? How to tell? are there other symptoms for Parkinson's?? Any help...

A. The tremor (shaking body parts) of Parkinson disease appears during rest of the limb and disappears or weakens during active movement. Additionally, Parkinson's disease cause walking problems and slow movements.

Q. Should I go for the knife? I have essential tremor for many years, and in the last few years it seems nothing helps it, and although I tried all the drugs my doctor could offer me, nothing helps. It really ruins my life, and recently I read about a surgery that suppose to treat it, called thalamotomy- does anyone know anything about it?

A. It's a possibility, and considered effective (reducing tremor in most of the patients). However, it has quite serious side effects, that can result even in weakness of some parts of your body. You should think really good before you opt for this treatment. Good luck!
