She tries to avoid sleep aids but finds herself lying awake for hours, hoping for a few hours of rest. Nothing seems to help. She has reported that her mother and her brother also have insomnia.

She believes it is something she has inherited from her mother, and new evidence published in SLEEP suggests this may be true. Is insomnia something inherited from family or is it a learned behavior? This question comes up for sleep providers often. Insomnia is defined as difficulty falling asleep, staying asleep or waking early and feeling unrefreshed from sleep.

There is some thought that specific genes are responsible for insomnia and a life changing event in childhood may trigger those genes and cause insomnia. This list does not include every symptom that has been described in the condition.

Symptoms of FFI may include: [1] [2] [4] Inability to fall asleep or stay asleep insomnia Difficulty thinking and concentrating cognitive impairment Short-term memory loss Weight loss Difficulty coordinating movements High blood pressure Inability to maintain body temperature Excessive sweating and tearing The first symptoms of FFI usually begin between the ages of 40 and 60 years.

Initial symptoms usually include difficulty sleeping and problems with thinking and concentration. The insomnia gets worse over time, leading to high blood pressure, rapid heart rate, weight loss, and trouble controlling body temperature.

Other symptoms that may develop include uncoordinated movements ataxia , hallucinations , severe confusion delirium , and difficulty swallowing. Death usually occurs within months after symptoms begin. Death is usually due to heart problems or infections.

DNA changes known as pathogenic variants are responsible for making genes work incorrectly or sometimes, not at all. Inheritance Inheritance. Fatal familial insomnia FFI is inherited in an autosomal dominant pattern. Autosomal means the gene is found on one of the numbered chromosomes found in both sexes.

Dominant means that only one altered copy of a gene is necessary to have the condition. The variant can be inherited from either parent. Sometimes an autosomal dominant condition occurs because of a new genetic variant de novo , and there is no history of this condition in the family.

Typically, children who inherit a dominant variant will have the condition, but they may be more or less severely affected than their parent. Sometimes a person may have a gene variant for an autosomal dominant condition and show no signs or symptoms of the condition. Diagnosis Diagnosis.

Fatal familial insomnia FFI is diagnosed based on the symptoms, clinical exam, a sleep study polysomnography , and imaging tests. The results of genetic testing may be helpful to help confirm the diagnosis.

The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
