This article is still missing information.
Hemisensory syndrome refers to having an altered sensation on one side of the body. There is no weakness, homonymous hemianopia, aphasia, agnosia, or apraxia. A related concept is nondermatomal somatosensory deficits (NDSD) which refer to regional, hemibody, or quadratomal sensory changes.[1] NDSDs are common in patients with widespread chronic pain.[2]
Classification
Complete hemisensory syndrome: affects the entire face, arm, and leg. The trunk may or may not be involved.
Incomplete hemisensory syndrome: includes variants such as cheiro-oral-cural syndrome, cheiro-oral syndrome, and isolated oral syndrome.
Aetiology and Associations
- Idiopathic (the most common)
- Migraine
- Depression and anxiety
- Nociplastic pain states such as CRPS[3][4][5], and Fibromyalgia[6]. Can be increased sensitivity i.e. allodynia on the ipsilateral side rather than decreased.
- Myaesthenia gravis (case report)[7]
- Carpal tunnel syndrome (single case)[8]
- Pure sensory strokes[9]
- Thalamus: ventral posterior nucleus which interconnects with the primary somatosensory cortex. e.g. Déjerine-Roussy syndrome
- Internal capsule: posterior quarter of the posterior limb where the sensory tracts without motor fibres are found.
- Parietal lobe
- Corona radiata
- Pons: paramedian dorsolateral region
Clinical Features
Symptoms can be positive and/or negative. Positive symptoms are the presence of paraesthesias or dysaesthesias such as pins and needles, pricking, tightening, or burning. Negative symptoms are anaesthesia or hypoaesthesia.[9]
In non-organic disease there is often an exact splitting at the midline. Organic disease can also have this pattern, however typically there is a paramedian distribution in this setting due to overlap of the intercostal nerves by 1-2cm.[8] A classic sign of a non-organic aetiology is loss of vibration sense over one side of the sternum.
Strokes of the ventral posterior nucleus is associated with contralateral hemisensory deficit involve mechanical, temperature, and noxious sensations.[8]
In patients with chronic pain-related NDSD there is subtle ipsilateral hyposensitivity to touch and temperature, mild to moderate depression, and a history of prolonged severe emotional distress. The symptoms are generally stable over time.[1]
Imaging
The standard modality is MRI brain which should include diffusion weighted images. An attenuation of apparent diffusion coefficent is consistent with ischaemic stroke.
Stroke was the cause for 3% in one study,[8], and 22% in another study.[9] In the later study, symptom onset of under 24 hours was the strongest predictor of ischaemic stroke (OR 31.4). A history of smoking (OR 7.3) and to a lesser extent older age (OR 1.14) was also more common in those with ischaemic stroke.
