Same Condition, Different Battle

For a long time, my journey with Hypokalemic Periodic Paralysis looked very different than it does today.

It’s actually been several years since I last experienced a true paralysis episode. When paralysis was more common for me, it mostly affected me from the waist down. I couldn’t stand or walk, but I was still able to use my arms and speak. In nearly four decades, only a small number of my episodes affected my entire body.

Those episodes could last anywhere from six hours to three days, with my longest stretching to ten days. They were intense, unpredictable, and often frightening. But there was also a pattern I came to understand.

After each episode, I would rebound. I’d return to my normal strength and often have many good days in between. There were stretches of time where I could truly feel like myself again.

Now, things have changed.
Instead of those longer, more defined paralysis episodes, I’m experience weakness much more frequently. It shows up almost daily, and no two days are the same. Some days it is mild and manageable. Other days, it is much heavier and more limiting.

One of the biggest differences is that this weakness affects both my arms and my legs. That’s very different from what I experienced before. Along with that comes an all-encompassing fatigue that is hard to put into words unless you have lived it. It’s not just being tired. It’s a deep, whole body exhaustion that follows me throughout the day.

These ongoing weakness episodes are less visible than paralysis, but in many ways they’re more constant and more disruptive. There are fewer clear breaks. I don’t always get those longer stretches of feeling completely normal anymore.

And in an honest moment, I find myself thinking something I’d never expected to say. I would rather be paralyzed from the waist down than deal with this constant, full body weakness and fatigue. Even though I can still move, and I know that matters, this version feels more debilitating in a different way. It’s harder to push through something that never really lets up.

This stage of my journey requires a different kind of resilience. It’s not about recovering from one major episode, but about adapting day by day, listening to my body, and adjusting to whatever each day brings.

Even though my symptoms look different now than they did before, this condition is still very much a part of my life.
It’s simply changed its form.

People with periodic paralysis can sometimes have an episode even when their potassium level is in the normal range.

Periodic paralysis can look different from person to person. Potassium levels are often part of the evaluation, but a normal result does not always mean someone is not having an attack. The timing of the blood test, the type of periodic paralysis, and each person’s pattern of symptoms can all affect what shows up.

That is why it is important to look at the whole picture, not just one lab result. Keeping track of symptoms, triggers, and how episodes change over time can help people and their doctors better understand what is happening.

OUR FAMILY’S HISTORY WITH ATS

Our family has been dealing with ATS for three generations. This is our family’s story and how the disease was discovered.

My mother (born in 1967) first experienced symptoms of PP at the age of nine, when the triggering factor was likely an influenza infection. The attacks then occurred at one-year intervals. Seven to ten days of paralysis, which gradually worsened until she could no longer walk, and then gradually subsided.
At the time, in Czechoslovakia, it was not possible to travel abroad or consult with foreign experts. Doctors in our country did not know how to treat such a disease. My mother spent many vacations in the hospital, both as a child and later on, but no diagnosis was ever found.
With the onset of menstruation, when she was 11 years old, the attacks became linked to her cycle (usually about a week to ten days before, and then improvement came with the onset of menstruation, though there were also attacks that lasted significantly longer).
At first, only my mother’s legs would go numb; gradually, as she aged, other muscle groups were affected—her arms, back, neck, face… Currently, her attacks are milder, but they focus more on her internal organs (heart, stomach, intestines).

My mother studied theology in college. Thanks to some professors’ contacts with the Western world, particularly with the Diakonie in Geneva, they managed to secure a so-called “Freie wissenschaftliche Bett” for her at a hospital in Würzburg in January 1989.
She was also able to travel to what was then West Germany. In Würzburg, she was diagnosed with hypoPP (with the help of a facility in Munich, where they performed a muscle biopsy).
My mother was prescribed Diclofenamide, and even after returning home, she remained in contact with Professor Ricker. She brought a year’s supply of medication with her in her suitcase, and in January 1990 she was admitted for a follow-up hospital stay, which was already much easier (thanks to the change in circumstances that allowed her to travel).
In 1996, doctors at IKEM in Prague saved my mother by implanting a pacemaker, and six months later, a defibrillator as well. After many ups and downs and various complications, my mother now has a subcutaneous defibrillator implanted and is on disability retirement.

In 2003, a request came from Ulm, Germany, to collect blood samples from all relatives on my mother’s side to learn more. The result was a confirmed gene mutation for ATS in my mother (without prior heredity) and the same mutation in me with a 50% chance of inheritance; my older sister is healthy. A series of photographs, questionnaires, and letters followed. First with Professor Ricker, and later with Professor Lehmann-Horn.

I first experienced the attacks myself when I was 11 years old (roughly a year after the diagnosis). I first felt weakness in my hands at school while taking notes; once a year, I had a very severe attack in my legs lasting about 14 days. Over the course of two years, the attacks became more frequent, but not very severe. From the age of fifteen, they became linked to my menstrual cycle, just like my mother’s. Over time, however, the attacks became stronger and lasted longer (up to 14 days).Sometimes just my legs, sometimes my arms, or just my arms. As an adult, however, there were periods when the attacks were almost invisible on the outside. In recent years, though, they’ve started affecting my internal organs more as well (heart, stomach, intestines).
On top of all that, I’ve been diagnosed with ADHD since childhood.

Until I was 15, I managed without medication. Then my mom and I both took a drug called Fenamid, which we were able to import from Italy. But they stopped manufacturing it after a few years, and we went without medication for about a month. That was tough. I could only move around well around the time of my menstrual cycle; otherwise, I was like a rag doll. Our doctor at the time prescribed Diluran, a Czech-made medication. It’s a drug for intraocular pressure that contains acetazolamide. Thanks to it, we can move around. The medication has quite a few side effects; one of them is a burning pain or even temporary loss of sensation in the soles of the feet and palms when the dose is increased during an attack.

Today, I am almost 32 years old and have two children. Both births were high-risk (I gave birth naturally to both), and I never had contractions throughout my entire abdomen—only in the lower part. My older son (born 2019) is healthy, but my younger daughter (born 2022) inherited ATS. A DNA test shortly after her birth confirmed it. About a year and three months ago, the disease manifested in her as well; she wasn’t even three years old yet. The attack was very severe; her legs became completely paralyzed, and it took three days before she was able to stand on them again with full strength. Since then, she’s needed to be watched closely. She’s very active. During hikes in rough terrain, she quickly runs out of energy. Fortunately, it doesn’t lead to complete paralysis, and so far, it’s enough for her to just rest.
We’re all under the care of geneticists, neurologists, and cardiologists (my daughter is currently just being monitored). I’m on beta-blockers (nadolol), which have been sufficient so far.
Despite all this, my mother and I try to live a full life, and I try to ensure the same for my daughter. Although I am also on disability, I still go to work, devote myself to my family and my dogs as best I can, and do everything I still have the strength for.

• Periodic Paralysis (PP) refers to a group of Channelopathies and are usually genetically inherited. They can causes sudden episodes of muscle weakness, stiffness, or paralysis. These attacks can affect the whole body or just 1 or 2 limbs.

This set of Channelopathies can cause temporary muscle weakness or paralysis. Things like exercise, stress, anxiety, certain types of food even being cold or hot are a few of the things that can trigger these episodes.

In some cases the heart and respiratory system can be affected.

The Periodic Paralyses involve defects in ion channels. These are gateways that let charged minerals (ions) such as sodium and potassium flow into and out of your cells. This flow of ions is a central part of how your muscles work. In PP, the ion channels sometimes fail, and the muscle cells don’t work correctly.

Depending on the form of PP that you have, the symptoms may be mild or severe, and they may last
from minutes to days. Sometimes, the disease may slowly get worse over time and cause permanent muscle damage.

Types of Periodic Paralysis:

Hypokalemic Periodic Paralysis (HypoPP) formally known as Westphall disease.
-A rare genetic, muscle channelopathy characterized by recurrent episodic attacks of generalized muscle weakness associated with a decrease in blood potassium levels.

Hyperkalemic Periodic Paralysis (HyperPP) formally known as Gamstorp disease.
-A rare muscle disorder characterized by episodic attacks of muscle weakness associated with an increase in serum potassium concentration.

Andersen Tawil Syndrome (ATS)
-A disorder that causes episodes of muscle weakness (periodic paralysis), changes in heart rhythm (arrhythmia), and dysphoric features.

Paramyotonia congenita (PMC)
-A rare non-progressive genetic disorder that affects the skeletal muscles. Affected individuals experience spells of muscle stiffness or when the muscles do not relax after contracting.

• Did You Know?
There is no cure yet for primary periodic paralysis, but some people are able to reduce attacks with careful trigger management and medication.
——🦓💪
Primary periodic paralysis is a lifelong condition, and while there is not yet a cure, there are ways to help manage it. Many people find that learning their triggers, making careful changes to diet or activity, and working closely with their doctor can lower the number of attacks they have. Medications may also help reduce attack frequency and severity for some people.
Because periodic paralysis can affect people differently, treatment is not one-size-fits-all. What helps one person may not help another, which is why it is so important to keep track of patterns and work with a provider who understands the condition.

•Periodic paralysis is a group of rare genetic disorders called channelopathies. These conditions cause sudden episodes of muscle weakness, stiffness, or paralysis. Attacks may affect the entire body or just one or two limbs.

The issue lies in the ion channels, gateways that move minerals like sodium and potassium in and out of muscle cells. When these gateways don’t work properly, muscles can’t contract as they should, leading to temporary weakness or paralysis that can last from minutes to days.

Episodes might be triggered by exercise, stress, rest after, temperature changes, or certain foods. In rare cases, the heart or breathing muscles can be affected too. Triggers vary, so keeping a journal often helps identify your own patterns.

Life with periodic paralysis can be unpredictable. You may walk freely one moment and suddenly need assistance the next. Work, driving, and family time can stop without warning. Because the symptoms come and go, others may think you look fine, which often delays understanding and diagnosis.

Types of Periodic Paralysis:
-Hypokalemic Periodic Paralysis (HypoPP) – Decreased blood potassium causes episodes of muscle weakness.
-Hyperkalemic Periodic Paralysis (HyperPP) – Increased potassium levels trigger temporary muscle weakness.
-Andersen Tawil Syndrome (ATS) – Periodic paralysis with irregular heart rhythms and distinct physical features.
-Paramyotonia Congenita (PMC) – Muscle stiffness and delayed relaxation after contraction.

• Did you know hypokalemic periodic paralysis comes in several different forms?

Hypokalemic periodic paralysis includes genetic, secondary, and atypical forms, each with distinct features.

• HypoPP Type 1 results from changes in the CACNA1S gene. This affects calcium channels in muscle cells.

• HypoPP Type 2 results from changes in the SCN4A gene. This impacts sodium channels in muscle cells.

• Secondary HypoPP results from non-genetic causes. Thyrotoxic periodic paralysis comes from an overactive thyroid. Kidney related potassium losses include renal tubular acidosis, Gitelman syndrome, Bartter syndrome, and hyperaldosteronism. Gastrointestinal issues like vomiting or diarrhea cause potassium loss. Medications such as diuretics lead to low potassium episodes.

• Atypical HypoPP results from unusual presentations. Late onset attacks occur later in life. Respiratory muscle weakness affects breathing. Myalgia or cramps happen during episodes. Prolonged weakness lasts longer than typical attacks. Episodes occur with normal potassium levels. These often link to rare gene variants like RYR1.

All these types of hypokalemic periodic paralysis can cause episodes of muscle weakness or paralysis during periods of low blood potassium, even though their root causes differ.

Common triggers include rest after exercise, high carbohydrate meals, or stress.

They require tailored tests and treatments like acetazolamide for genetic forms or thyroid management for secondary ones.

• People with periodic paralysis live with unpredictable changes in muscle strength, tone, and control. These episodes may come and go without warning, sometimes lasting minutes, hours, or even days.

The cause lies in faulty ion channels, which are tiny pathways in the muscles that help control electrical signals. When these channels do not work properly, muscles can become weak, stiff, or temporarily paralyzed.

There are several forms including Hypokalemic and Hyperkalemic Periodic Paralysis, Andersen Tawil Syndrome, and Paramyotonia Congenita. Each affects people differently, but all share one thing: a body that sometimes runs out of “charge.”

The battery image below reminds us that even when strength fluctuates, resilience and understanding are constant. -RB
