Understanding Dementia and Early identification

Understanding Dementia and Early identification

Dementia a growing concern with the aging population- A perspective   DEMENTIA Dementia isn’t a specific disease. Instead, it describes a group of symptoms affecting memory, thinking and social abilities severely enough to interfere with daily functioning. Though dementia generally involves memory loss, memory loss has different causes– Alzheimer’s disease which accounts for 60 to 80% of cases. Vascular dementia which occurs after stroke is the second common type of dementia. Thyroid problems. Vitamin deficiencies. Dementia with Lewy bodies(DLB). Mixed dementia. Frontotemporal dementia. Creutzfeldt-Jakob disease. Normal pressure hydrocephalus. Huntington’s Disease….

Understanding Pain biology

The International Association for Study of Pain defines “pain as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage.” It is important to note here that pain is not only a physical sensation but may also be an emotional experience.  Pain need not always be associated with tissue damage; it may also occur when there is potential tissue damage or even when there is no actual tissue damage (referred to as neuropathic pain). However, pain is an important mechanism…

Diabetes Neuropathy

Diabetes Neuropathy

DIABETIC NEUROPATHY Diabetic neuropathy refers to nerve disorders associated with diabetes.  About 60 to 70% of people with diabetes have some form of nerve problems.  Nerve problems due to diabetes can occur in every organ including digestive tract, heart and sex organs.  People with diabetes can develop neuropathies at any time but the risk rises with age and longer duration of diabetes. WHAT CAUSES DIABETIC NEUROPATHY Diabetic neuropathy seems to be related to blood sugar level being too high for too long leading to nerve damage.  Nerve damage is likely…

GLOBAL PERSPECTIVE ON GENETICALLY MODIFIED CROPS

GLOBAL PERSPECTIVE ON GENETICALLY MODIFIED CROPS

 Earlier plants with favourable features were produced by breeding techniques which took several years and involved repeated sexual crossings over several generations, but nowadays transgenic plants or GM plants are produced using recombinant DNA technology which involves genetically modifying the plants to express genes that are not native to the plant or modifying endogenous genes.  As a result of this technology crops have been engineered to be resistant to abiotic and biotic stresses. Despite the benefits mentioned above several NGO and media organisations are opposed to GM plants terming them…

ESTABLISHED BIOMARKERS OF BREAST CANCER

ESTABLISHED BIOMARKERS OF BREAST CANCER

Breast cancer is one of the leading causes of cancer-related deaths in women, but over the past few decades there has been a sustained decline in mortality rates due to incremental application of increasingly effective adjuvant medical treatments and regular mammography screening programs.  Mammography screening has led to detection of early-stage (<2 cm) node-negative breast cancer and has certainly contributed to improved outcomes, but there are still many challenges for clinicians regarding the choice of optimal adjuvant treatment, avoidance of overtreatment in patients who only receive a modest benefit, while suffering…
