For example, CDT failure has been shown to be a state dependent feature of major depression. 10-12 Recent studies undermine this notion, however. Conceptually, clock drawing has been viewed as a visuospatial task, sensitive to right perietal pathology. Unfortunately, CDTs still have both conceptual and practical limitations. 5 9 Moreover, CDTs are rapid and well accepted. 8 The severity of clock drawing failures progresses over time in Alzheimer’s disease, and correlates with longitudinal changes in cognitive testing.
1-7CDTs have been found to correlate significantly with traditional cognitive measures 1 2 4 5 and to discriminate healthy from demented elderly patients. There is a growing interest in the potential of clock drawing tests (CDTs) as a screen for cognitive impairment. The pattern of CLOX failures may discriminate clinical dementia subgroups. It is strongly associated with cognitive test scores. CLOX subscales discriminated between patients with Alzheimer’s disease and elderly controls (83.1% of cases correctly classified Wilkes’ lambda=0.48, p<0.001), and between Alzheimer’s disease subgroups with and without constructional impairment (91.9% of cases correctly classified Wilkes’ lambda=0.31, p<0.001).ĬONCLUSIONS The CLOX is an internally consistent measure that is easy to administer and displays good inter-rater reliability. Only the MMSE significantly contributed to CLOX2 scores ( F(4,72)= 57.2, p<0.001 R 2=0.74).
The EXIT25 accounted for 68% of CLOX1 variance. EXIT25 and MMSE scores predicted CLOX1 scores independently of age or education ( F(4,82)=50.7, p<0.001 R 2=0.71). RESULTS In elderly subjects, CLOX subscores correlated strongly with cognitive severity (CLOX1: r=−0.83 v the EXIT25 CLOX2: r=0.85 v the MMSE). Between rater reliability (27 subjects) was high for both subtests. The CLOX is divided into an unprompted task that is sensitive to executive control (CLOX1) and a copied version that is not (CLOX2). METHODS Subjects received the CLOX, an executive test (EXIT25), and the mini mental state examination (MMSE). The clock drawing performance of elderly patients was compared with that of 62 young adult controls. SUBJECTS 90 elderly subjects were studied (45 elderly and well persons from the independent living apartments of a continuing care retirement community and 45 patients with probable Alzheimer’s disease). It can be configured by rookies and professionals alike.OBJECTIVE To describe a clock drawing task (CLOX) designed to elicit executive impairment and discriminate it from non-executive constructional failure. It comes with support for several useful configuration settings for altering the appearance of the clock in case you get bored of the same old layout. The bottom line is that Analog Desktop Clock helps you enhance the looks of your desktop with a handy analogue clock. It remains light on system resources so you do not have to worry that it hampers the overall performance of your computer. Tests have pointed out that Analog Desktop Clock carries out a task quickly and without errors. Other important customization options worth being mentioned enable you to change the color of the outline, background, digits, and arrows, show the day of the week and date, apply effects to the digits and arrows, as well as reveal a second hand with a custom color.
CLOCKX 1.6 WINDOWS
What’s more, you are allowed to keep the clock on top of other programs, launch the tool at Windows startup, set the transparency of the clock with the aid of a built-in slider, and adjust the size of the clock. You can access the program’s configuration parameters by clicking on the dedicated Settings icon, which is displayed near the analogue clock.Īnalog Desktop Clock offers you the possibility to change the background image of the clock with the aid of several preset photos or import pictures from your personal collection (e.g. You cannot appeal to a help manual, but you can tweak the dedicated parameters on your own because they look easy to work with. You are allowed to place the clock anywhere on the screen using drag-and-drop actions. You need to go through a simple and fast installation process in order to gain access to the analogue clock.
