During the summer, high temperatures in Spain and other countries can intensify the symptoms of various neurological conditions. At our center, many patients with Filum Disease, Arnold-Chiari I Syndrome, idiopathic Syringomyelia, and Neuro-cranio-vertebral Syndrome report increased discomfort and symptom exacerbation during periods of intense heat.
Why can heat worsen neurological symptoms?
In general, heat can aggravate the symptoms of pre-existing neurological disorders. Extreme temperatures place additional stress and increase the risk of heat-related illness, especially in people with neurological or psychiatric conditions, as well as in children, the elderly, and people with chronic diseases.
Under normal conditions, the body maintains its internal temperature between 36.7°C and 37°C through a process known as thermoregulation, which is coordinated by the hypothalamus. When environmental temperatures rise, the body must work harder to dissipate excess heat. If heat exposure exceeds the body's ability to compensate, thermoregulation becomes less effective.
Heat stress can also impair neuronal transmission, leading to disorientation, confusion, or even loss of consciousness, in addition to intensifying other existing neurological symptoms.
Heat and Arnold-Chiari I Syndrome
In patients with Arnold-Chiari I syndrome, headache is one of the most common symptoms. During periods of intense heat, there is a risk of increased pain attacks, as high temperatures promote the dilation of cerebral blood vessels, causing the characteristic throbbing pain and further limiting daily activities.
Hot weather can also interfere with restful sleep, leading to insomnia or worsening pre-existing sleep disturbances. Lack of sleep, in turn, can trigger new migraine attacks.
The neuronal dysfunction caused by heat stress can also worsen memory, concentration, and mood—functions that may already be impaired in patients with Filum Disease.
High Temperatures and Idiopathic Syringomyelia
In patients with idiopathic syringomyelia, excessive heat may intensify symptoms such as chronic fatigue, pain, paresthesia, limb weakness, mobility difficulties, and altered sensitivity to temperature and touch.
High temperatures increase fatigue, worsen sensitivity alterations and, along with excessive sweating and stifling environment, can further limit the mobility and independence of these patients.
Recommendations During the Summer
As with other groups particularly vulnerable to heat, the following measures are recommended during the summer months:
- Maintain adequate hydration.
- Avoid sun exposure during the hottest hours of the day.
- Stay in air-conditioned or well-ventilated environments whenever possible.
Patients with conditions related to Filum Disease are also advised to plan their outings and activities and avoid going out alone. Being accompanied can help ensure prompt assistance if symptoms worsen while away from a cool, safe environment.
Following Filum System® treatment
After the Filum System® surgery, performed on over 2,500 patients with Neuro-cranio-vertebral Syndrome by Dr. Miguel B. Royo-Salvador’s team at the Institut Chiari & Siringomielia & Escoliosis de Barcelona, changes in thermoregulation and circulation are among the numerous observed postoperative improvements.
Furthermore, symptoms such as headaches, insomnia, cognitive or mood disturbances, chronic fatigue, loss of strength, pain, and mobility problems can be alleviated or even disappear after treatment. As a result, some patients may experience greater tolerance to high temperatures after treatment.
We look forward to seeing you in Barcelona
If you are planning to visit our center this summer for an initial consultation or a follow-up appointment, following these recommendations can help you stay comfortable and enjoy Barcelona, its coastline and the Mediterranean climate, while receiving specialized care from our medical team.
