Shaking hands or a noticeable tremor can have many different causes, including excessive caffeine use or benign essential tremor as well as other neurologic conditions. These conditions may be linked to sleep disturbances, or insomnia and sleep disorders may be present at the same time due to a different cause. Pay attention to your symptoms, and seek the advice of a doctor if you are concerned about any symptoms.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Tremor is the involuntary movements of one or more parts of the body. Causes of tremor include neurological disorders, neurodegenerative diseases, drugs, mercury poisoning, overactive thyroid and liver failure. There are several types of tremor. Treatment depends upon the type of tremor and availability of medications for the condition.
Depression is an illness that involves the body, mood, and thoughts and affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things. The principal types of depression are major depression, dysthymia, and bipolar disease (also called manic-depressive disease).
Stress occurs when forces from the outside world impinge on the individual. Stress is a normal part of life. However, over-stress, can be harmful. There is now speculation, as well as some evidence, that points to the abnormal stress responses as being involved in causing various diseases or conditions.
Caffeine is a stimulant, which may be found in beverages, supplements, and medications. Common food sources include coffee, chocolate, green tea, and soft drinks. While caffeine addiction is not considered a real addiction, it can cause withdrawal symptoms, such as headache, tiredness, decreased energy, sleepiness, depressed mood, and more.
