Addiction is defined as a chronic, relapsing brain disease that is characterized by compulsive drug seeking and use, despite harmful consequences.â  It is considered a brain disease because drugs change the brainâthey change its structure and how it works.. Volkow and H. Schelbert. Addiction is a lot like other diseases, such as heart disease. Both disrupt the normal, healthy functioning of the underlying organ, have serious harmful consequences, and are preventable and treatable, but if left untreated, can last a lifetime.
What are the possible causes of pulmonary consolidation? Answer: Pulmonary consolidation is a term used in olden days for lobar pneumonia. Normally the lungs are filled with air, and they are spongy but in condition like pneumonia, the lung space gets filled up by liquid and pus and the debris of the dead tissues instead of gas.
The connective tissue is the tissue that holds the air sacs together. Interstitial lung disease happens when the lung parenchyma is damaged in some way and inflammation occurs. Changes in the parenchyma and connective tissue happen when the inflammation is chronic.
