Chronic Rapid Eyelid-twitching / Eye-blinking - Brief Medical Explanations
In terms of chronic rapid eyelid-twitching / eye-blinking, it's actually called Blepharospasm which is a symptom of involuntary and uncontrollable movements in the muscles around a person's eyes which in turn make them appear like 'blinking non-stop' to other people.
In certain cases, this may be caused by myasthenia (muscular weakness) in the eyes
organ as a result of stresses, overstraining of the eyes, lacks of sleeps, the serious lacks of certain nutrients / minerals to support the normal functionings / movements of your eyelid
muscles etc.
Next, in the case whereby no stress, any kinds of viral / parasital / bacteria infections, overstraining of the eyes etc are involved whilst the eyelids and the entire organs just look superficially normal and ok, and at the same time, the eyelid-twitching / eye-blinking just get 'unexplainedly' from bad to worse from time to time, such medical scenarios could actually be caused by other neuromuscular disorders which are much more complicated.
And in terms of such neuromuscular disorders, they may arise as a neurological / Tardive Dyskinesia side effect of certain medications, especially the powerful mind-altering tranquilizers of antipsychotics / neuroleptics, particularly when such medications are over-relied on to the point of sheer abuse.
In such a connection, please consider the following excerpts : -
"Chlorpromazine ( a type of antipsychotic / neuroleptic meant for mental disorders) side effects :
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop taking chlorpromazine and call your doctor at once if you have a serious side effect such as:
twitching or uncontrollable movements of your eyes, lips, tongue, face, arms, or
legs;"

Follow Up : Tardive Dyskinesia (Chronic Rapid Eyelid-twitching /Eye-blinking Is One of The Common Symptoms)
Please consider the following excerpts about Tardive Dyskinesia ( of which one of the most common symptoms is purposeless uncontrollable rapid eye-blinking / eyelid-twitching)
"Tardive dyskinesia is a variety of dyskinesia (involuntary, repetitive movements) manifesting as a side effect of long-term or high-dose use of dopamine antagonists, usually antipsychotics. Other dopamine antagonists that can cause tardive dyskinesia are drugs for gastrointestinal disorders (e.g. metoclopramide) and neurological disorders. While newer atypical antipsychotics such as olanzapine and risperidone appear to have less dystonic effects, only clozapine has been shown to have a lower risk of tardive dyskinesia than older antipsychotics"
"Tardive dyskinesia is characterized by repetitive, involuntary, purposeless movements.
Features of the disorder may include grimacing, tongue protrusion, lip
smacking, puckering and pursing of the lips, and rapid eye blinking. Rapid
movements of the extremities may also occur. Impaired movements of the fingers may also appear. For comparison, patients with Parkinson's disease have difficulty moving, while patients with tardive dyskinesia have difficulty not moving."

Please take note that for such chronic rapid eyelid-twitching / eye-blinking caused by neurological / neuromuscular / Tardive Dyskinesia side effects of medications, the MRI and other related medical imaging examinations would not show anything abnormal / problematic at all given that bodily chemical imbalances (interferrences with the synaptic activities of the neurons / neurotransmitters chemicals such as dopamine etc by the related nerve-disturbing medications) cannot be conclusively and definitely observed and diagnosed by such MRI or other related medical imaging examinations at all.
In short, for the medical scenario of chronic rapid eyelid-twitching / eye-blinking syptom caused by medicational nerve-disturbing side effects of Tardive Dyskinesia, the MRI and other related medical imaging examinations would not be able to reveal, observe and diagnose anything at all.
Follow-up - Mental Disorders : Brief Analysis and My Opinions Of Dealing With Them
Actually, one thing to take note here is that the chemical imbalance in the brain (especially mood-regulator, Serotonin) leading to the mental disorder is actually caused by disturbances to one's mood in the very first place that might arise as a result of various emotionally unpleasant / unacceptable factors, scenarios, events, persons, surroundings, etc that are considered upsetting, distressing and even traumatic to certain people (resulting thus in disturbances to the normal functionings of neurotransmitter chemical, Serotonin and then such chemical imbalance in the brain). All in all, the question as to whether a person facing or confronting with such emotionally unpleasant / unacceptable factors, scenarios, events, persons, surroundings, etc will eventually suffer from mental disorder or not, that would largely and mostly depend on how good or how bad one is able to tolerate, put up and adapt oneself to all such emotionally unpleasant / unacceptable adversities without getting emotionally disturbed in the end.
Next, for drugs such as anti-depressants and anti-anxieties (for neurosis - less serious mental disorder) and antipsychotics / neuroleptics (for psychosis- more serious mental disorder characterized by serious hallucinations, and in fact, the powerful mind-altering agents), they are in fact a simplified way of chemical solution to various mental disorders.
In such a connection, their chemical mechanism is such that they would serve to artificially block the negative nerve impulses (negative thoughts, feelings, emotions etc) from getting sent to the brain, and thus temporarily stop a person from getting upset, distressed, depressed etc throughout the effective period of the each drug dosage (that may last for mere hours). In the process of doing so and given the fact that the entire mechanism is purely artificial by drug interception rather than natural, the synaptic activities of the neurons and the neurotrasmitters chemicals especially Serotonin and Dopamine (the neurotransmitter chemical responsible for human bodily movements) etc of the nervous systems would unavoidably be interferred and antagonized in the end.
Subsequently, such a phenomenon would then eventually lead to certain neurological / neuromuscular and in the worst case scenario, the neuro-degenerative symptoms getting developed as the side effects of these drugs for mental disorders. And hence, modern medical science actually tries to overcome such these problems by inventing the more and more advanced versions of the newer and better drugs with ever-decreasing harmful side effects from time to time for the sake of the health cares and well-beings of the ones using them.
At the same time, another thing to take note as well is such that since the human bodies would gradually develop tolerances for any medications, including the ones for mental disorders, and especially the ones that are fed to them repeatedly over the long-term, such medications for mental disorders would hence become addictive themselves whereby larger and larger dosages would gradually be required from time to time to achieve the similar therapeutical effects, and then eventually, they would lose their intended artificial curative effects particularly when they are over-relied upon to the point of sheer abuse whilst no other non-medicational efforts are taken to deal with such mental disorders.
As such, given the ultimately inevitable risks of side effects of such drugs, my opinions are such that the more practical and realistic solution to mental disorders is such that whilst taking the related drugs to curb and bring down the uncontrollable symptoms of mental disorders, such as feelings of deep depressions, deep hallucinations, violent emotional outbursts etc, as well as making the necessary efforts to benefit oneself to the best possible extent from the newer and better drugs with ever-decreasing harmful neurological side effects for such mental disorders which are invented from time to time by the modern medical science, such medications should be used wisely with all the precautionary measures. Whilst at the same time, other non-medicational efforts of emotional and communication supports from the others etc to cheer and brighten up one's mood and spirit as well as the related self-control efforts (to control one's mood and tempers) should thus also be taken at the same time to deal with such mental disorders more effectively towards the goals of gradual improvements as well as final and full recoveries.
