Why can the body feel tremors? Is it a feature of age, or can it happen at any time? Are involuntary movements always Parkinson’s? or they can be hint of something,
There are several concerns that appear when talking about tremors, above all associated with Ramiro Heredia, a clinical physician at the Hospital de Clínicas.
And he adds: “They can be a separate entity, or can be part of a disease.”
Tremors: what are they and types
Tremor is defined as movement of a part of the body involuntary and rhythmic. It is caused by the contraction of opposing muscles, both synchronously and alternately. Generally, it affects the hands or the head, although it can affect any part of the body,” explains the doctor.
Meanwhile, Ricardo Maiola, a neurologist at the Parkinson’s and Abnormal Movements Program of the same institute, explains: “Tremors are very frequent abnormal movements in daily life, they are divided into two large groups: physiological and pathological, The difference is that the latter may alter daily activities, while the former are those that are present from a very young age, and do not represent a problem.”
Neurologists point out that, in turn, pathological tremors are divided Three big groups: loss of the rest (When the body is not moving, it is relaxed) sedentary (for example, if it appears when you extend your arm or perform a certain activity such as grasping an object), and intentionally (occurs before a definite action, as when the tip of the nose is touched with the index finger).
Heredia says: “You can also classify according to its distributionie, depending on which part of the body it is, if it is localized (for example, in the arm) or generalized, and if it is symmetric (it affects both parts of the body equally) or asymmetric (it affects one half the body, more than the other)”.
due to shock
As indicated, tremors may be physiological (that is, present in a healthy person without any disease), to be caused by a great Diversity Diseases, drugs, substances or toxic agents, among other causes.
Most common tremors are seen in handsAlthough they can affect the head, legs, trunk, vocal cords, any part of the body.
Heredia lists, “They can be of genetic origin, that is, the father or mother of the person who suffers from it has the same condition; acquired; or idiopathic, without any apparent reason that justifies it.”
However, it is important to be aware that, if they recur over time without a clear or obvious reason, it is facilitative. seek medical advice bedside, clinical, family or generalist, “so they can evaluate tremors from a holistic perspective,” he advises.
“Shiver should be evaluated in a clinical context“, he suggests. And although he clarifies that this is not necessary in all cases: “After the clinical examination, some patients are indicated to consult a neurologist.”
Tremors: What Symptoms Can They Be?
Although it is difficult to generalize, Heredia lists what the underlying diseases are. more common,
The most frequent cause of tremor (that is, tremor that is not resting) occurs when for some reason the so-called “normal body tremors”,
“We all have a tremor that is physical, imperceptible, but triggered in certain situations, such as drugs, drugs, alcohol, caffeine, inhalation drugs such as salbutamol, used to treat asthma attacks, anxiety, fear, fatigue , or hormonal disorders such as hyperthyroidism, fever; it becomes clear And sometimes leads to the doctor’s office”, he lists.
However, action tremor can also have a pathological cause: “These are the people who suffer from essential tremor Or gentle In fact, it can affect up to a 5% of the populationUsually from the age of 30-40, with a father or mother of the same status”, he specifies.
It is not related to Parkinson’s disease, and is, in fact, benign tremor. 4 times more Compared to this disease, since the prevalence is 3 to 4 cases per thousand inhabitants per year.
Maiola indicates that essential or mild tremor is the most frequent pathological cause of tremor and has a “partial response” to the large number of drugs that may be indicated to treat it.
However, as Maiola explained, the most frequent reason for tremor at rest It is actually Parkinson’s disease. it’s trending 1 case per thousand inhabitants per year, says Heredia.
“it is Most common cause of tremor at rest, and is one of the ghosts of patients suffering from tremors. This is accompanied by other clinical signs, such as slowing of movement (bradykinesia), rigidity, and postural instability,” he explains.
To diagnose it, “the main thing is medical evaluation“, he stresses, since there is no imaging or laboratory test that can detect Parkinson’s disease itself, it is rather diagnosed using a variety of diagnostic criteria, always ruling out other causes of the symptoms. doing, such as using drugs.
However, to support the diagnosis, “many patients will require laboratory tests, imaging of the nervous system, and sometimes functional tests,” he says.
Tremors: When to Consult
“You must always be consulted before a tremor, whether it represents a disease or not, because if it appears at some point in life that was not present before, need to rule out the underlying diseaseOr that the tremor is the cause of all discomfort, as is the case with essential tremor,” says the neurologist.
Heredia concluded, “A medical history and a thorough physical exam should be done. It is also taken into account how well it responds to certain treatments.”
