Does destruction of the brain causes sleep disorder?

Yes, destruction of certain areas of the brain can lead to sleep disorders. The brain plays a crucial role in regulating sleep patterns and cycles, so damage to specific regions can disrupt this process. For example, damage to the hypothalamus, which controls the sleep-wake cycle, can result in conditions such as insomnia or excessive daytime sleepiness. Additionally, brain injuries or diseases that affect neurotransmitter levels or communication between brain regions can also lead to sleep disturbances.
