Tests and diagnosis

By Mayo Clinic Staff

Unless you live alone and are completely unaware of your sleepwalking, chances are you'll make the diagnosis of sleepwalking for yourself. If your child sleepwalks, you'll know it.

Your doctor may do a physical or psychological exam to identify any conditions that may be confused with sleepwalking, such as nighttime seizures, other sleep disorders or panic attacks. In some cases, a sleep study in an overnight sleep lab may be recommended.

Sleep studies

To participate in a sleep study, also known as a polysomnogram, you'll likely spend the night in a sleep lab. A technologist places sensors on your scalp, temples, chest and legs using a mild adhesive, such as glue or tape. The sensors are connected by wires to a computer. A small clip is placed on your finger or ear to monitor the level of oxygen in your blood.

Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during the study. Technologists monitor you throughout the night while you sleep.

Your doctor will review the information to determine whether you have any sleep disorders.
