Interstitial lung disease Interstitial lung disease Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), is a group of lung diseases affecting the interstitium (the tissue and space around the air sacs of the lungs). It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, perivascular and perilymphatic tissues. It may occur when an injury to the lungs triggers an abnormal healing response. Ordinarily, the body generates just the right amount of tissue to repair damage. But in interstitial lung disease, the repair process goes awry and the tissue around the air sacs (alveoli) becomes scarred and thickened. This makes it more difficult
Lewy body dementia with Parkinson's disease, and according to his widow he experienced depression, anxiety, and increasing paranoia. Upon autopsy his widow said he was found to have diffuse DLB. Ian G. McKeith, a dementia researcher and professor of old age psychiatry, commented that DLB was still too little known, and that Williams' symptoms were explained by DLB. The LBDA clarified the distinction between the term used in the autopsy report, "diffuse Lewy body dementia"—which is more commonly called "diffuse Lewy body disease" and refers to the underlying disease process—and the umbrella term, "Lewy body dementia," which encompasses both PDD and DLB.
