What is the best treatment for chronic insomnia?

Cognitive behavioral therapy for insomnia (CBT-I) can help you control or eliminate negative thoughts and actions that keep you awake and is generally recommended as the first line of treatment for people with insomnia. Typically, CBT-I is equally or more effective than sleep medications.

What is the best medication for insomnia and anxiety?

Antidepressants: Some antidepressant drugs, such as trazodone (Desyrel), are very good at treating sleeplessness and anxiety. Benzodiazepines: These older sleeping pills — emazepam (Restoril), triazolam (Halcion), and others — may be useful when you want an insomnia medication that stays in the system longer.

How do I fight anxiety and insomnia?

What are biomarkers and why are they useful?

What are biomarkers and why are they useful?

Biomarkers are useful in a number of ways, including measuring the progress of disease, evaluating the most effective therapeutic regimes for a particular cancer type, and establishing long-term susceptibility to cancer or its recurrence. The parameter can be chemical, physical or biological.

What do biomarkers measure?

The term biomarker, or biological marker, refers to a broad range of measures which capture what is happening in a cell or organism at a given moment. Biomarkers are objective medical signs (as opposed to symptoms reported by the patient) used to measure the presence or progress of disease, or the effects of treatment.
