Sleep Apnea: This condition is characterized by pauses in breathing or periods of shallow breathing during sleep, leading to non-reparative sleep. Sleep movements and abnormal sounds (like snoring) are common, and night sweats can occur due to the stress of interrupted sleep.

Restless Leg Syndrome (RLS): Characterized by an irresistible urge to move the legs, usually due to uncomfortable sensations. It can lead to sleep movements and non-reparative sleep. Abnormal sounds might not be directly related, but night sweats can occur due to the stress and discomfort.
Periodic Limb Movement Disorder (PLMD): Involves involuntary movement of the legs or arms during sleep, disrupting sleep and potentially causing night sweats due to the physical exertion and stress of these movements.
REM Sleep Behavior Disorder (RBD): Patients act out their dreams, leading to sleep movements and potentially abnormal sounds. Non-reparative sleep and night sweats can result from the intense physical activity during sleep.

Seizure Disorders: Nocturnal seizures can cause abnormal movements, sounds, and night sweats. Although less common, missing this diagnosis could have significant consequences, including injury during seizures and the underlying risk of the seizure disorder itself.
Panic Disorder: Nighttime panic attacks can lead to non-reparative sleep, abnormal sounds (e.g., screaming), and night sweats. While the primary issue is psychological, the physical manifestations during sleep can mimic other sleep disorders.
Hyperthyroidism: Can cause night sweats, sleep disturbances, and potentially lead to movements or sounds during sleep due to increased metabolism and nervous system activity.

Kleine-Levin Syndrome: A rare disorder characterized by recurring periods of excessive daytime sleepiness and automatic behavior. Sleep movements and abnormal sounds might occur, and the stress of these episodes could lead to night sweats.
Fatal Familial Insomnia (FFI): An extremely rare genetic degenerative brain disorder that leads to severe insomnia and other neurological symptoms, including movements and possibly abnormal sounds during the little sleep that occurs, with night sweats due to the body's extreme distress.
Sleep-Related Eating Disorder: Involves eating during sleep, which can lead to abnormal sounds and movements. Non-reparative sleep and night sweats might result from the physical activity and potential psychological distress associated with these episodes.
