Iâm pregnant and have had a blood test for chickenpox. The blood test can show that you: 1  Are immune (have already had varicella disease or varicella vaccine) and have no sign of recent infection. You have nothing further to be concerned about.  Are not immune and have not yet been infected.
Causes of acute insomnia can include: 1  Significant life stress (job loss or change, death of a loved one, divorce, moving) 2  Illness. 3  Emotional or physical discomfort.  Environmental factors like noise, light, or extreme temperatures (hot or cold) that interfere with sleep.
The patient died at 58 (seven months after the onset of symptoms). An autopsy was completed post-mortem which revealed mild atrophy of the frontal cortex and moderate atrophy of the thalamus. The atrophy of the thalamus is one of the most common signs of fatal familial insomnia.
