is a major factor that can precipitate Fibromyalgia.
Medically it is known that stress can affect the
hypothalamic-pituitary-adrenal axis (link between the brain and our
hormonal glands) axis and bring about changes in the cortisol level,
According to EEG studies, there is an impairment in the non-Rapid-Eye-Movement, or non-REM sleep
in individuals with FM.
Any condition that hampers stage 4 sleep,such as depression
or certain medications may aggravate the situation.
There is a low level of dopamine
in patients with fibromyalgia. Dopamine inhibits pain perception; in FM
patients, low levels of dopamine are released in response to pain,
thereby, heightening their ability to sense pain.
The level of serotonin in the
brain is also relatively low in patients with fibromyalgia.
Researchers have found elevated levels of a sensory neurotransmitter,
called substance P
in the spinal fluid of FM patients. This nerve chemical is involved in
the transmission of message involving pain, touch and temperature from
the body to the brain.
