Neuropathic pain is the sensation of pain due to abnormal discharges of impaired or injured neural structures in the peripheral &/or central nervous system.
It is characterized by hyperesthesia, hyperalgesia and allodynia.
Common neuropathic pain syndromes are central neuropathic pain, painful diabetic peripheral neuropathy, postherpetic neuralgia, trigeminal neuralgia, postsurgical neuropathic pain, HIV-related neuropathy, lumbosacral radiculopathy and complex regional pain syndrome.
Adolescents appear to have disordered normal brain growth trajectories after initiating drinking, with or without co-use of marijuana, a recent study has found. Peak consumption in the past year and family history of alcoholism possibly contribute to abnormal cortical volume trajectories.
