Yes, and this connection is often underestimated. Sleep is when the brain does much of its repair work, clearing waste byproducts and consolidating memory. When sleep is disrupted after a brain injury, that repair process can slow down, which may extend recovery time and worsen daytime symptoms like fatigue and brain fog.

We often see a cycle where:

• Injury disrupts normal sleep architecture
• Poor sleep worsens cognitive symptoms and mood
• Worsened symptoms make it harder to fall or stay asleep
• The cycle continues unless it's addressed directly

This is part of why we integrate sleep evaluation into our recovery plans rather than treating it as a separate issue. Addressing sleep can meaningfully support the rest of the healing process.
