Central post-stroke pain is a rare central neuropathic pain also known as Dejerine Roussy syndrome, and thalamic pain syndrome occurs after infarction of the ventroposterolateral thalamus.

The syndrome was named after them after their deaths. In general, the term central post-stroke pain is now preferred to describe the neuropathic pain after stroke as thalamic syndrome cannot be considered synonymous with all central pains. Any vascular lesion or disease involving the central somatosensory system carrying pain either slow or fast fibers can cause these symptoms. Although an ischemic event precedes most central post-stroke pain, the pain can also happen after hemorrhagic stroke which can be either intracerebral or subarachnoid hemorrhage.

Intracerebral hemorrhage can precede central post-stroke pain in the legs because of the pattern of arrangement of fibers to face, arm, trunk, and leg is mediolateral, in the ventral posterior nucleus of the thalamus. The central post-stroke pain occurs more frequently in those with acute stroke and larger lesions, but no characteristic finding on computed tomography CT brain scan of the patients with central post-stroke pain is identified.

Dejerine-Roussy Syndrome

Brain magnetic resonance imaging MRI of patients with this syndrome has shown infarctions, while single-photon emission computed tomography shows decreased blood flow, especially to the left thalamus.

The onset of pain symptoms may vary from days to years after having a stroke. Most frequently the symptoms start within the first 6 months but can develop after 10 years of infarction. Central post-stroke pain after lateral medullary infarction may occur sub-acutely with the average time span of 4 weeks range 1 to 24 weeks. There is the difficulty in assessing the incidence of central post-stroke pain due to confounding the effect of other causes of chronic pain in stroke patients, for example, shoulder pain, painful shoulder spasticity, primary headaches like a tension-type headache, or various musculoskeletal pains particularly affecting knees and hips.

Goussy incidence and duration of central post-stroke pain are not related deherine gender or age of the patient nor the side of the lesion. Diffusion tensor tractography DTT shows a 3-dimensional view and estimation of the function of the spinothalamic tract.

Any lesion on the spinothalamic tract, anywhere throughout its course in the central nervous system CNScan cause central post-stroke pain. There are several etiologic theories proposed which include central imbalance, central disinhibition, central sensitization, the Grill illusion theory or thalamic changes, and the inflammatory response of the neural pathway involved.

Another proposed pathway of central imbalance is at the dejerinr of third level neurons of the spinothalamic pathway. Those project from thalamus to the insular cortex or anterior cingulate region, although the mechanism is undefined.

The ventral posterolateral nucleus of the thalamus has an intrinsic network of GABAergic neurons, which causes the intrinsic inhibition of ventral posterolateral nucleus. Stroke affecting the lateral thalamus causes central disinhibition by the deafferentation of the thalamic nucleus, which causes the activation of cortical areas resulting in pain.

The disinhibition of temperature-sensing fibers primarily those that sense cold might be the cause of cold allodynia. Central sensitization is the increased synaptic dejerije of the central afferent neurons leads to spontaneous pain or nociception on suboptimal stimulus. A spontaneous bursting pattern of multifocal asynchronous xejerine activity has been recorded in the deafferented thalamic nuclei, with the help of microelectrodes, in patients of central post-stroke pain.

The N-methyl-D-aspartate receptor antagonists ketamine has helped the central pain in animal models. This provides indirect evidence for the damage of central neurons from N-methyl-D-aspartate-receptor activation in central sensitization. Central post-stroke pain is a kind of hemidystonia that typically involves the areas of the body affected by stroke.

This pain is a sharp, burning, and stabbing pain with the intensity of somewhere between 3 to 6 on a numeric rating scale of 0 to 10 rroussy being the worst pain imaginablealong with hyperalgesia dejeine allodynia.

The patient may even complain of one or more types of pain. The quality of pain varies and is often described as pricking, aching, lancinating, shooting, squeezing, freezing, lacerating, electrical, cold, numb, swollen, cutting, dull, and throbbing. It is difficult for the patient sometimes to describe the quality of pain. Central post-stroke pain is often split into three components.

First can be a spontaneous, constant pain described as burning, aching, pricking, freezing, and squeezing. This component may be the predominant complaint as it happens daily with pain-free intervals of a few hours.

Any eoussy may experience one or more of these components of this neuropathic pain. The management of central post-stroke pain requires a multidisciplinary approach and includes various pharmacological antidepressants, anticonvulsants, opioids, N-methyl D-aspartate receptor antagonists, and miscellaneous therapies and non-pharmacological options. Drjerine have shown that amitryptiline rousys mg is superior to carbamazepine, according to a three-phase crossover randomized clinical trial. Amitryptiline is started from low doses of 10 to 20 mg per roissy, with weekly increment in dose, until the pain is relieved and the patient has no side effects anticholinergic effects.

Pain is relieved after 4 to 7 days of reaching the optimal dose. Selective serotonin reuptake inhibitors foussy not been tried for central poststroke pain. If antidepressants are not effective, an anticonvulsant like carbamazepine is added, especially if the pain is sharp and lancinating.

Somnolence and dizziness are dejerinw most common side effects of carbamazepine. Gabapentin is effective for both central or peripheral origin neuropathic pain, with an optimal daily dose of mg.

It is particularly effective for the spontaneous intermittent component of pain or thermal allodynia. Long-term use may cause weight gain.

A single trial has shown that lamotrigine is moderately effective in central poststroke pain.

If antidepressants and anticonvulsants are not effective alone or in combination opioids may be considered. Intravenously-infused tramadol was found effective in patients with chronic central poststroke pain. Intravenous ketamine is reserved for the refractory cases of central poststroke pain. Repetitive transcranial magnetic stimulation r TMS: It is a motor cortex stimulation technique which is noninvasive dejdrine has a long-lasting effect.

Overall results to relieve pain in the patients are variable but encouraging. Transcutaneous electrical nerve stimulation TENS: Especially low-frequency TENS is found to effective in combination with social support and family education. Deep brain stimulation DBS: It is an option of treatment in a limited number of patients. As ablation of any area of the brain might cause other deficits or even aggravates the pain.

Antiplatelet medications especially cilostazol dejerind have a role in the treatment of central post-stroke pain. The thalamic hemorrhagic stroke makes cilostazol easier to pass through the blood-brain barrier, due to disruption of the barrier at the site of hemorrhage. The exact mechanism of action for relieving thalamic pain is unknown. It is found to be effective, but more trials are needed. Other modalities such as psychotherapy, behavioral therapy and educating patient and family about various coping strategies are also considered.

Central Sensitization Central sensitization is the increased synaptic efficacy of the central afferent neurons leads to spontaneous pain or nociception on suboptimal stimulus. History and Physical Central post-stroke pain is a kind of hemidystonia that typically involves the areas of the body affected by stroke.

Evaluation The diagnosis should be based on the following components: History onset, location, intensity, duration, quality, aggravating factors.

Clinical and sensory examination toussy map the sensory abnormality and to rule out the other causes of pain. Confirmation of a central nervous system lesion through imaging or negative or positive sensory signs confined to the area of the body corresponding to the lesion. Other causes of pain, such as nociceptive or peripheral neuropathic pain, are excluded or considered highly unlikely.

Descriptors such as burning, painful cold, electric shocks, aching, pressing, stinging, and pins dejernie needles, although all pain descriptors can apply.

Henriette Klit and his co-workers propose a stepwise approach. Antidepressants Studies have shown that amitryptiline 75 mg is superior to carbamazepine, according dejefine a three-phase crossover randomized clinical trial.

Anticonvulsants If antidepressants are not effective, an anticonvulsant like carbamazepine is added, especially if the pain is sharp and lancinating.

Opioids If antidepressants and anticonvulsants are not effective alone or in combination opioids may be considered. Various Invasive and Non-Invasive Non-Pharmacological Roussh The following are available for managing the patients but have variable efficacy. Future of Central Poststroke Pain Management Antiplatelet medications especially cilostazol may have a role in the treatment of central post-stroke pain.
