The October Slide: What Seasonal Changes Mean for Neurological Symptoms

By Lisa Brekke, PT, DPT

Have you ever noticed that your dizziness, migraines, brain fog, or other neurological symptoms seem to worsen around October? You’re not alone. Many people living with neurological conditions, such as migraine, vestibular disorders, multiple sclerosis, or post-concussion symptoms, report a seasonal dip in how they feel during the fall months. This phenomenon is sometimes called the “October Slide.”

Why Does This Happen?

There isn’t just one cause, but several factors seem to play a role:

1. Changing Light Exposure

• Shorter days mean less sunlight, which can affect circadian rhythms and sleep quality.

• Decreased daylight also impacts vitamin D levels and mood, both of which influence neurological health.

2. Weather Shifts

• Fluctuating barometric pressure and cooler temperatures are well-known migraine triggers.

• Rapid changes in weather can also worsen dizziness, fatigue, and pain in some neurological conditions.

3. Immune System Stress

• Fall marks the start of cold and flu season. Viral infections and immune system activation can temporarily worsen neurological symptoms.

4. Lifestyle Changes

• Busier schedules, back-to-school routines, and upcoming holidays add stress.

• Less outdoor activity and exercise compared to summer can lower resilience to symptom flares.

What Can You Do About It?

The October Slide doesn’t have to take you by surprise. A few proactive strategies can make a big difference:

• Prioritize sleep: Stick to a consistent bedtime and consider light therapy to support circadian rhythms.

• Stay active: Even short walks outdoors help with balance, mood, and energy.

• Manage triggers: Keep a symptom diary to see how weather or seasonal changes affect you.

• Support your immune system: Hydrate, eat nutrient-rich foods, and talk with your provider about supplements like vitamin D.

• Plan ahead: Recognize that October may be a tougher month and build in more rest and recovery time.

A Seasonal Reminder

If you’ve felt your symptoms creeping up as we move into the fall season, know that it’s not “all in your head.” The October Slide is real for many people with neurological conditions.

For patients, the “October slide” highlights that symptom flare-ups and setbacks are often part of the journey—not signs of failure. Through mentoring, providers gain the tools and education they need to recognize these patterns and guide patients with reassurance, strategies, and support to navigate this dip with confidence.
