Sleep scientists say that:

• recognition memory for faces is unaffected by sleep loss. A person who has not slept for as much as 35 hours can perform as well as someone who is not sleep deprived.
• the area of the brain that controls temporal memory can be affected by prolonged sleep loss and/or ageing. So a healthy 65 year old who sleeps normally would be able to perform this test similarly to a 20 year old who has gone without sleep for 36 hours.
