Non-therapeutic approach: a benefit for psychological health!

Psychological symptom may be pronounced at any stage of life. Advanced technology such as nuclear medicine imaging method (positron emission tomography) has already stated that some neurotransmitters (chemical substances in the brain) have vast role in controlling human psychological status, synchronizing the brain and mind (emotion). Therefore, it is acknowledged that the emotion is mostly influenced by the higher brain function. There is therapeutic option (psychiatric medication) to prevent this psychological disorder in the medical procedure. However, some non-therapeutic approaches may have beneficial effects on higher brain function for modulating psychological symptoms. Body mind training (BMT) such as ‘deep breathing exercise’ is one useful non-therapeutic approach for psychological disorder, I suggest.

Hypertension and Lacunar stroke!

I would like to focus on hypertension-inducing brain stroke. There is always a chance of initiating brain stroke, suffering from malignant hypertension (MHTN). In the chronic stage (MHTN), there might be infarction of deep-brain structures, which is called lacunar stroke. Usually, deep structures of the brain are mostly involved in lacunar stroke, which is caused by the blockage of small arteries of deep brain.
Once this lacunar stroke is developed, it might be symptomless or mild symptoms are pronounced such as mild loss of sensation in the face, limbs or other parts of the body (sensory symptoms). MRI imaging method is useful to find out the lacunar stroke related deep brain lesions among the patients suffering from MHTN. However, it is useful to control chronic hypertension (MHTN) to prevent from lacular stroke.

Symptomless disease!

I desire to write about one devastating pathogenesis of major artery of human – carotid artery stenosis. I use to mention this stenosis carotid artery as carotid artery disease (CAD). The most devastating feature relating with clinical symptom is that this carotid artery stenosis sometime reveals symptomless, which is harmful for developing cerebral ischaemia. If we consider about medical problems that persuading carotid artery stenosis, cardiac disease (CD) or hypertension (HTN) are mentioned. Therefore, in regular medical check up of CD or HTN, it is wise to arrange one bed side examination of carotid arteries using US imaging method (ultrasound imaging).
