A patient and doctor discuss congenital insensitivity to pain. For people with this disorder, cognition and sensation are otherwise normal; for instance, patients can still feel discriminative touch (though not always temperature [3]), and there are generally no detectable physical abnormalities.
Since people with this condition are unable to sweat, they are unable to properly regulate their body temperature. [1] Those affected are unable to feel pain and temperature. [2] [3] The absence of pain experienced by people with CIPA puts them at high risk for accidental self-injury. Corneal ulceration occurs due to lack of protective impulses ...
Marsili syndrome is an extremely rare genetic disorder which is characterized by symptoms similar to those reported on individuals with congenital insensitivity to pain with anhidrosis. It can be fatal if it goes unnoticed/undiagnosed.
The first sign of HSAN2 is usually numbness in the hands and feet. Soon after, affected individuals lose the ability to feel pain or sense hot and cold. People with HSAN2 often develop open sores (ulcers) on their hands and feet. Because affected individuals cannot feel the pain of these sores, they may not seek treatment right away.
Familial dysautonomia (FD), also known as Riley–Day syndrome, is a rare, [2] progressive, [3] recessive genetic disorder of the autonomic nervous system [2] that affects the development and survival of sensory, sympathetic, and some parasympathetic neurons in the autonomic and sensory nervous system.
Complex regional pain syndrome is characterized by pain that is distributed regionally, usually starts in an extremity distally, occurs after a trauma, and is disproportionate in severity or duration compared to the expected course of the trauma — the sites affected by complex regional pain syndrome experience autonomic and inflammatory changes.
“The event or death may have been related to the underlying disease being treated, may have been caused by some other product being used at the same time, or may have occurred for other reasons.” The Times story also cited a buprenorphine study by researchers in Sweden that looked at “100 autopsies where buprenorphine had been detected.”
Locked-in syndrome may mimic loss of consciousness in patients, or, in the case that respiratory control is lost, may even resemble death. People are also unable to actuate standard motor responses such as withdrawal from pain; as a result, testing often requires making requests of the patient such as blinking or vertical eye movement.
