Impairment can also be caused by cytotoxic factors such as chemotherapy. It has been proposed that even common tinnitus and the attendant hearing frequency-gaps masked by the perceived sounds may cause erroneous proprioceptive information to the balance and comprehension centers of the brain, precipitating mild confusion.

Brown-Séquard syndrome (also known as Brown-Séquard's hemiplegia, Brown-Séquard's paralysis, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis, or spinal hemiparaplegia) is caused by damage to one half of the spinal cord, i.e. hemisection of the spinal cord resulting in paralysis and loss of proprioception on the same (or ipsilateral) side as the injury or lesion, and loss of ...
Vitamin B 12 deficiency may cause, among several neurological abnormalities, overlapping cerebellar and sensory ataxia. [28] Neuropsychological symptoms may include sense loss, difficulty in proprioception, poor balance, loss of sensation in the feet, changes in reflexes, dementia, and psychosis, which can be reversible with treatment.

Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature. Understanding the mechanisms behind these selective lesions requires a brief discussion of the anatomy involved.
The causes of nerve damage are grouped into categories including those due to paraneoplastic causes (neuropathy secondary to cancer), immune mediated, infectious, inherited or degenerative causes and those due to toxin exposure. In idiopathic sensory neuronopathy no cause is identified. Idiopathic causes account for about 50% of cases. [2]
The absence of proprioception or two-point tactile discrimination on one side of the body suggests injury to the contralateral side of the primary somatosensory cortex. However, depending on the extent of the injury, damage can range in loss of proprioception of an individual limb or the entire body.
impairment of tactile sensation; impairment of proprioception, i.e. postural sensation and sensation of passive movement; sensory and visual neglect syndromes, i.e. inability to pay attention to things in certain parts of the person's sensory or spatial environment; this may be as extreme as denial of a limb
This rare syndrome causes the loss of proprioception and sense of vibration below the level of injury [27] while motor function and sensation of pain, temperature, and touch remain intact. [34] Usually posterior cord injuries result from insults like disease or vitamin deficiency rather than trauma. [35]
