Movement disorders are a group of neurological conditions that can cause atypical movements, along with other symptoms. One of the most well-known movement disorders is penyakit Parkinson (PD), a neurodegenerative condition which affects the central nervous system. However, roughly 30 other conditions—including essential tremor, Huntington's disease, Wilson's disease, and dystonia—are also considered movement disorders. While more rare and less often discussed, these come together to make up the vast majority of movement disorder cases. While an estimated 42 million Americans are currently living with a movement disorder, just one million of those cases are diagnosed as Parkinson's disease.

Now, experts are drawing attention to a symptom which is closely linked with one of these rarer conditions. They say that if you notice this particular symptom in your arms and legs—or even in your face—your doctor may be able to follow up with a blood test to distinguish between this condition and several other movement disorders with overlapping features. Read on to learn why this symptom is considered a major red flag, and what to expect as your doctor works toward a diagnosis.

Because so many movement disorders share symptoms, and because these symptoms often begin subtly and worsen over time, they can be difficult to diagnose. To complicate matters further, some of the most well-known movement disorders cannot be diagnosed based on a single test or the presence of any one symptom.

For instance, if Parkinson's disease is suspected, a neurologist must evaluate symptoms and medical history, and perform a neurological and physical examination. It is possible to meet the criteria for a Parkinson's diagnosis if another movement disorder is actually to blame.

This lack of sufficient diagnostic testing translates into a high rate of misdiagnosis in movement disorders. In fact, a 2006 study published inJAMA Neurology found that one in three subjects presenting with tremor was misdiagnosed as having essential tremor, when their true diagnosis was Parkinson's.

"Karena adano conclusive screening or test, patients with very early Parkinson's disease may not meet the clinical diagnosis criteria. On the flip side, this lack of specificity means that you could be diagnosed with Parkinson's disease, only to find out later that you have a different condition that mimics Parkinson's," write Johns Hopkins experts, who were not associated with the JAMA belajar.

For this reason, your doctor should rule out the movement disorders that bisa be screened with a blood test and other diagnostic testing to inch you closer to a conclusive diagnosis.

One particular movement disorder that bisa menjadiconfirmed with a blood test is is Huntington's disease, a rare, progressive brain disorder that affects movement, mood, and thinking skills. Experts warn that if you experience chorea, a symptom characterized by involuntary jerking movement in the arms, legs, or face, it's a good idea to request a screening. According to the Alzheimer's Association, this involuntary limb movement is among the most common signs of Huntington's disease,AE0FCC31AE342FD3A1346EBB1F342FCB.

Huntington's disease is a genetic disorder, and can be inherited from just one parent. Diagnostic blood testing is especially important if you show symptoms and do not have a complete family medical history available to you.

Those with incomplete family histories can also look for additional signs of Huntington's disease which may help to distinguish it from other movement disorders.

The Mayo Clinic notes that Huntington's patients typically present with three main types of symptoms : fisik, kognitif, dan psikiatris. Mereka yang mempengaruhi gerakan fisik meliputi masalah otot, gerakan mata yang lambat, gangguan gaya berjalan, dan kesulitan bicara. Mereka yang mempengaruhi kemampuan kognitif termasuk kurangnya kontrol impuls, kelambatan dalam pemrosesan bahasa, kesulitan belajar, kurangnya fleksibilitas, dan kesulitan fokus pada tugas. Dan akhirnya, mereka yang mempengaruhi satu keadaan kejiwaan termasuk depresi, penarikan, kelelahan, insomnia, dan banyak lagi. Bicaralah dengan dokter Anda tentang skrining untuk gangguan gerakan Huntington atau terkait jika Anda melihat adanya perubahan seperti ini.
