Hyperkalemic periodic paralysis is a condition that causes episodes of extreme muscle weakness or paralysis, usually beginning in infancy or early childhood. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Episodes tend to increase in frequency until mid-adulthood, after which they occur less frequently in many people with the condition. Factors that can trigger attacks include rest after exercise, potassium-rich foods such as bananas and potatoes, stress, fatigue, alcohol, pregnancy, exposure to hot or cold temperatures, certain medications, and periods without food (fasting). Muscle strength usually returns to normal between attacks, although many affected people continue to experience mild stiffness (myotonia), particularly in muscles of the face and hands.

Hyperkalemic periodic paralysis is a condition that causes episodes of extreme muscle weakness or paralysis, usually beginning in infancy or early childhood. Most often, these episodes involve a temporary inability to move muscles in the arms and legs. Episodes tend to increase in frequency until mid-adulthood, after which they occur less frequently in many people with the condition. Factors that can trigger attacks include rest after exercise, potassium-rich foods such as bananas and potatoes, stress, fatigue, alcohol, pregnancy, exposure to hot or cold temperatures, certain medications, and periods without food (fasting). Muscle strength usually returns to normal between attacks, although many affected people continue to experience mild stiffness (myotonia), particularly in muscles of the face and hands.
Most people with hyperkalemic periodic paralysis have increased levels of potassium in their blood (hyperkalemia) during attacks. Hyperkalemia results when the weak or paralyzed muscles release potassium ions into the bloodstream. In other cases, attacks are associated with normal blood potassium levels (normokalemia). Ingesting potassium can trigger attacks in affected individuals, even if blood potassium levels do not go up.

Patient information leaflet
Hyponatraemia
Hyponatraemia is a low level of sodium in the blood. Sodium levels in the blood have to be tightly controlled. Too rapid correction of hyponatraemia can cause a condition called central pontine myelinolysis. Symptoms occur 2-4 days after onset and may present with paralysis of all four limbs (quadriplegia). This has been seen more often in those.

Återuppfödningssyndrom
Återuppfödningssyndrom was first described in Far East prisoners after the second world war when they developed hjärtsvikt after starting to eat again after a prolonged period of starvation. What is refeeding syndrome. Återuppfödningssyndrom is a dangerous and life threatening shift of fluids and body salts (electrolytes) that can occur when.

Patient information leaflet
Spina bifida
In most cases of myelomeningocele, surgery can be carried out to close the defect. However, damage to the nervous system will usually already have taken place. The nerve damage can cause a range of symptoms, including weakness (paralysis) of the legs and loss of feeling in the skin of the legs. There may also be problems with passing wee (urine).

Encefalit
Encefalit is inflammation of the brain. It is usually caused by a viral infection. In the UK, the most common virus to cause encephalitis is herpes simplex virus. Symptoms usually start with the common symptoms of a viral infection such as high temperature (fever), headache, muscle... Stiff neck and back. Intolerance of light (photophobia)..
