These surgeries target portions of the brain associated with mood disorders and pain. Deep brain stimulation (DBS) is another possible treatment that works by stimulating parts of the brain related to behavior and emotion to relieve the psychological cause of the pain. [9]
The etiology and mechanism of pain are related to the cause of the pain. Certain forms of neuropathic pain are associated with lesions to the central nervous system such as thalamic pain associated with certain lesions (for instance strokes) to the thalamus [ 81 ] whereas other forms of pain have a peripheral inciting injury such as traumatic ...
Another way to modulate the transmission of pain information is via descending fibers from the brain. These fibers act through different interneurons to block the transmission of information from the nociceptors to secondary neurons. [6] Both of these mechanisms for pain modulation have been implicated in the pathology of allodynia. Several ...
Some advocate that, because similar brain regions are involved in both physical pain and psychological pain, pain should be seen as a continuum that ranges from purely physical to purely psychological. [26] Moreover, many sources mention the fact that many metaphors of physical pain are used to refer to psychologically painful experiences.
Headaches and pain can occur as a result of a brain injury, either directly from the damage or due to neurological conditions stemming from the injury. Due to the changes in the brain as well as the issues associated with the change in physical and mental capacity, depression and low self-esteem are common side effects that can be treated with ...
Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury. [4]
Nociplastic pain is a longterm complex pain, one of three mechanisms of pain, defined by the International Association for the Study of Pain as "pain that arises from altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain". [2]
Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.
