Progressive supranuclear palsy (PSP) is a rare neurological disorder that worsens over time and can lead to serious, life-threatening complications. The most significant of these include pneumonia, choking due to swallowing difficulties, and head injuries resulting from frequent falls. These complications are the primary causes of morbidity and mortality associated with progressive supranuclear palsy.

## Risks of Pneumonia and Choking

Swallowing problems (dysphagia) are common and severe symptoms in progressive supranuclear palsy, typically appearing earlier in the course of the disease compared to some other similar disorders [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>). Difficulty swallowing can cause food or liquids to enter the lungs instead of the stomach, leading to aspiration pneumonia, one of the most dangerous complications [\[2\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S2>). Furthermore, swallowing difficulties significantly increase the risk of choking, requiring immediate attention and medical care [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>).

To reduce these risks, doctors may recommend modifying the consistency of food and liquids to facilitate swallowing. In severe cases where the risk of choking or malnutrition is significant, physicians may resort to a surgical procedure to place a feeding tube directly into the stomach (gastrostomy) to ensure the patient receives necessary nutrition without the need for chewing and swallowing [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>).

## Frequent Fall Injuries

Loss of balance while walking is one of the most common initial symptoms of progressive supranuclear palsy and often leads to sudden, unexplained falls [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>). People with progressive supranuclear palsy are characterized by a tendency to fall backward, known as axial rigidity [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>). These frequent falls increase the risk of sustaining serious injuries, particularly head injuries, which can be life-threatening [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>).

To manage this issue, weighted walking aids can be used to help reduce the risk of falling backward [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>). Additionally, physical therapy and exercises supervised by a healthcare professional can help maintain joint flexibility and improve balance, thereby reducing the likelihood of falls [\[1\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S1>).

## Deterioration of Brain Functions and Malnutrition

As progressive supranuclear palsy advances, overall brain functions deteriorate, affecting cognitive and behavioral abilities [\[3\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S3>). This decline can lead to the need for around-the-clock care and monitoring as the patient loses brain functions [\[3\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S3>). Furthermore, severe swallowing problems can lead to malnutrition if not managed effectively, weakening the patient's general health and increasing their vulnerability to other complications [\[3\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S3>).

Although progressive supranuclear palsy itself is not directly life-threatening, the complications resulting from it are what increase the risks. With good care for medical and nutritional needs, many people with progressive supranuclear palsy can live for 10 years or more after the first symptoms of the disease appear [\[2\]](<https://clinicsjo.com/en/faq/what-are-the-most-serious-complications-associated-with-progressive-supranuclear-palsy#source-S2>).
