A six-year-old Ragdoll cat underwent examination due to a six-month history of slowly progressive gait abnormalities. The cat presented with an ambulatory tetraparesis with a neurological examination indicating a C1-T2 myelopathy. Radiographs of the spine showed a radiopaque irregular line ventrally in the vertebral canal dorsal to vertebral bodies C3-C5. In this area, magnetic resonance imagin...

We present two cases of painless urinary retention secondary to central intervertebral disc prolapse. In neither case were there signs or symptoms suggesting an underlying neurological insult. Both patients voided spontaneously following neurosurgical intervention. The classical features of acute cauda equina compression may be absent in patients with central lumbar disc protrusion. Painless ur...

A subtle impairment of motor coordination and sensory integration functions is frequently found in schizophrenia. Clinically these deficits present as neurological soft signs (NSS). Because of its crucial role in motor function, control of muscle tone and equilibrium, the cerebellum is likely to be involved in the appearance of NSS. Magnetic resonance imaging (MRI) was performed in 30 patients ...

The paper presents a new, experimental, wireless tremor telemonitoring system composed of an optional variable number of portable devices integrating three-axis acceleration mini-sensors which are connected to very small dimensions acquisition systems with Wi-Fi transmission capabilities. The main advantages of the design system consist of the possibilities to monitor simultaneously many body p...

Among 16 chronic schizophrenic in-patients, all had at least one neurological soft sign (NSS), and 6 (40%) had definite neurodysfunction. NSS and TD scores were highly intercorrelated, and NSS were significantly correlated with neuroleptic drug exposure. NSS correlated positively with both positive and negative symptoms and cognitive impairment but not with cerebral ventricular size on CT. Pati...

A concept of an endophenotype, also termed as an internal endophenotype, is used in genetic studies on psychiatric disorders. Neurological soft signs are also considered candidates for endophenotypes of schizophrenia. Neurological soft signs are, objectively measured, non-localizing abnormalities, not related to impairment of a specific brain region, reflecting improper cortical-subcorical and ...

Neurological soft signs (NSS), i.e., minor motor and sensory changes, are a common feature in psychiatric disorders related to brain changes. Nevertheless, they have rarely been investigated in patients with Alzheimer's disease (AD). NSS were examined in 104 nursing home residents with AD with respect to dementia severity, neuropsychiatric symptoms, and Parkinsonian signs as well as potential m...

Selenium is an essential micronutrient, although ingestion in excess in pigs can cause disease conditions including neurological dysfunction and chronic skin and hoof lesions. Controlled feeding trials in growing swine, using the same Se content in feed sources, resulted in higher concentrations (p < or = 0.05) of Se in blood and organs of pigs fed seleno-DL-methionine compared with those recei...
