Pseudoathetosis is a movement disorder, very similar to athetosis, in which the symptoms are not differentiable from those of actual athetosis, however the underlying cause is different. While actual athetosis is caused by damage to the brain, specifically in the basal ganglia, [4] pseudoathetosis is caused by the loss of proprioception. [17]
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.

In other childhood dementia disorders, early development may be slower than typical before declining. [12] This progressive decline causes difficulty concentrating, memory loss, confusion, and learning difficulties, [4] in addition to the loss of developmental skills acquired previously, such as: walking, talking, writing, reading, and playing.
An increased loss of balance is interpreted as a positive Romberg's test. The Romberg test is a test of the body's sense of positioning (proprioception), which requires healthy functioning of the dorsal columns of the spinal cord. [1] The Romberg test is used to investigate the cause of loss of motor coordination .
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.

Friedreich's ataxia (FRDA) is a rare, inherited, autosomal recessive neurodegenerative disorder that primarily affects the nervous system, causing progressive damage to the spinal cord, peripheral nerves, and cerebellum, leading to impaired muscle coordination . The condition typically manifests in childhood or adolescence, with initial ...
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.
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
