Post-IC Syndrome (PICS): Recognizing & Recovering from Invisible Illness

What is PICS? The Three Faces of an Invisible Condition

Post-intensive care syndrome (PICS) is a cluster of symptoms that can emerge after a stay in the intensive care unit (ICU). Experts, including those at Amsterdam UMC, attribute it to the profound impact of critical illness and the intensive treatments received. The symptoms generally fall into three categories:

• The Physical Fight: Loss of muscle strength, persistent fatigue and the feeling of being overwhelmingly heavy are common. Even simple tasks can require enormous effort. Chronic pain or shortness of breath also frequently occur.
• The ‘Brain Fog’: Memory lapses, difficulty concentrating, and heightened sensitivity to stimuli like light or sound are characteristic. It can feel as though the world is moving too quickly.
• The Mental Blow: Anxiety, sadness, and mood swings are normal reactions. In some cases, individuals may develop Post-Traumatic Stress Disorder (PTSD), with flashbacks and nightmares related to their ICU experience.

The Invisible Patient: Your Loved Ones Are Affected Too

Often overlooked is the fact that an ICU stay doesn’t just affect the patient. Family members, partners, and other loved ones can also experience trauma. The constant uncertainty and the confronting environment of the ICU can lead to similar symptoms, a phenomenon known as PICS-Family (PICS-F).

Former ICU patient Fons van der Voort shared a poignant detail on the NPO Radio 1 program Villa VdB. The only thing he said to his family over the phone was “sorry,” because he felt he had almost left them. This illustrates the deep emotional impact on the entire family.

The Road to Recovery: Where Do You Begin?

These physical, cognitive, and mental symptoms can feel overwhelming, for both the patient and the family. Knowing you need to do something is clear, but energy and clarity are lacking. Where do you start? We asked psychologist Marije Schoonbeek, specializing in the mental impact of severe illness.

“From my experience, the most important first step that a patient and their family can take to cope with the mental chaos after an ICU stay is…”

“What we see is that it’s often already difficult to recognize PICS properly and in time. Patients are often further along in their recovery process but continue to get stuck. This often leads to a lot of frustration before PICS is even considered. Good explanation is therefore essential to understand what has happened in your brain during an ICU stay. I always advise patients and family members to talk a lot about what happened during that ICU stay so that the stories of all those involved can ‘come together’. Creating a (photo) diary of all events or visiting the ICU and talking to a doctor or nurse who worked closely with the patient can also be very helpful in processing.”

Schoonbeek also suggested considering a rehabilitation trajectory if cognitive complaints persist.

Help and Recognition: You Are Not Alone

Beyond that crucial first mental step, practical support and connection with others who understand are vital. Good follow-up care after an ICU stay isn’t yet standard practice everywhere in the Netherlands. This represents where the national organization IC Connect plays a key role. They offer a listening ear, reliable information, and connect you with people who truly understand what you’re going through. They develop resources like the IC-HerstelWijzer (IC Recovery Guide) and tirelessly work to improve ICU aftercare throughout the Netherlands.

Conclusion: Be Kind to Yourself

The journey back after an ICU stay isn’t a quick race to the finish line; it’s a gradual process that requires time and, above all, a lot of patience. The most important first step, as psychologist Marije emphasizes, isn’t just recognizing the symptoms, but actively bringing the puzzle pieces together. The patient often has gaps in their memory, while the family experienced everything. By talking, reviewing a (photo) diary, or visiting the ICU together, you create one complete, shared story. This provides clarity, recognition, and is the starting point for processing. Remember that what you’re feeling is ‘normal’ after such a traumatic event. And remember: you don’t have to do it alone.
