Kidney disease associated with mental disorders --- diagnostic tests

Diagnosis: On the basis of the diagnosis of renal failure on , if found tiredness, weakness, reticent , less dynamic , unresponsive and other spiritual activities decline, should be considered early psychiatric symptoms of renal failure . Such as drowsiness , lethargy, delirium or euphoria, depression and flapping tremor , epileptic seizures , etc. , then the exclusion of other factors . Consider renal encephalopathy.

1 there is a clear history of kidney disease with renal failure symptoms , signs and laboratory tests positive evidence of ; to consciousness -based development and changes in psychiatric symptoms and renal failure is consistent . On the basis of the diagnosis of severe renal failure on , if found tiredness, weakness, lack of exercise, reticent , unresponsive and other spiritual activities subsided, when the blood of non -protein nitrogen and carbon dioxide combining power increased, should be considered a symbol of early renal failure when possible.

2 drowsiness , lethargy, delirium or euphoria, depression and flapping tremor , epileptic seizures .

3 After the exclusion of other factors that cause mental disorders , the diagnosis of renal encephalopathy can be established.

4 combined EEG changes when necessary , and to participate in the blood of non -protein nitrogen and carbon dioxide combining power and other indicators increased .

5 has been diagnosed with renal insufficiency, and a history of blood dialysis or peritoneal dialysis . In dialysis basis, if found depression, anxiety or less move, reticent , can be considered as associated with early signs of mental disorders when cold. Once a delirium or confusion, flapping tremor , epileptic seizures should be considered associated with the Department of dialysis imbalance syndrome, but must exclude mental disorders caused by other factors . Accompanied by EEG changes .

Laboratory tests: meets the primary kidney disease laboratory tests positive change.

Other laboratory examinations : EEG see basic rhythm slows , increased slow wave rhythm , synchronization of both sides of paroxysmal slow , α rhythm suppression and diffuse high amplitude slow waves , even seen in frontotemporal based paroxysmal slow , epileptic seizures waves. Hyperventilation test often makes slow increase. Renal encephalopathy deeper consciousness , it is becoming increasingly apparent EEG changes followed , unconsciousness can occur when δ wave significantly . EEG changes in severity as one of the signs of renal encephalopathy degree .

EEG shows high amplitude rhythmic symmetry group of dialysis δ waves , basic volatility increased , irregular slow wave . α -wave reduction also seen sharp waves , spikes appear. General pre-dialysis patients prone to severe abnormal EEG slow wave . Such EEG changes can be seen in dialysis 3h . 1 to 2 days after stopping dialysis in order to restore to the state before dialysis .
