In adults, causes of hypernatremia include hyperalimenation, dehydration secondary to either fever or elevated ambient temperature, NaHCO3 administration, and diabetes insipidus. The signs and symptoms of hypernatremia are variable, including seizures and depression of sensorium. Associated metabolic ...
Signs and Symptoms Symptoms of hypernatremia are similar to those of hyponatremia, because of effects that are again based primarily on the central nervous system.1,99 During hypernatremia, brain cells shrink substantially as water moves into the extracellular space. This situation can cause intrace...
Signs and symptoms of hypernatremia Symptoms of hypernatremia tend to be nonspecific. Anorexia, restlessness, nausea, and vomiting occur early. These symptoms are followed by altered mental status, lethargy or irritability, and, eventually, stupor or coma. Musculoskeletal symptoms may include twitchin...

Eccentric germinomas are rare but can be found in the basal ganglia, lobar, brainstem, and cranial vault. We present a 14-year-old boy who presented with signs and symptoms of overt diabetes insipidus and a radiological diagnosis of left frontal high-grade glioma. Confirmative histopathology ...
Management of hyponatremia In patients who require non-emergency treatment in the hospital setting: - In patients with chronic severe hyponatremia who have mild to moderate symptoms (eg, dizziness, forgetfulness, gait disturbance, nausea, vomiting, confusion, and lethargy), hypertonic saline (typically...
Symptoms of Hypernatremia Initial symptoms include lethargy, weakness and irritability Can progress to twitching, seizures, obtundation or coma Resulting decrease in brain volume can lead to rupture of cerebral veins leading to hemorrhage Severe symptoms usually occur with rapid increase to sodium concent...
We present a 14-year-old boy who presented with signs and symptoms of overt diabetes insipidus and a radiological diagnosis of left frontal high-grade glioma. Confirmative histopathology revealed germinoma. The patient had a resolution of hypernatremia post-surgery and maintained normal sodium ...
Nonspecific signs of hyponatremia include anorexia, nausea,vomiting, and generalized weakness. Acutely hyponatremic patients whose sodium level drops below 120 mEq/L during 24 to 48 hours may present with severe neurologic findings, including confusion, seizures, cerebral edema, coma, and brainstem ...
