This brief video provides an overview of some of the common misconceptions about Parkinson’s disease, including causes, course, and outcome. For example, a single head injury will not cause Parkinson’s disease, at least there is no scientific evidence of it occurring. However, repeated head injuries might result in someone who is predisposed to Parkinson’s appear with symptoms earlier than they otherwise would be. This is the same with any environmental factors, such as pesticides or heavy metals (researchers have not shown a solid link between environmental hazards and Parkinson’s disease).
Watch this brief video for a few other misconceptions about Parkinson’s disease.
As a follow-up to my previous post about some of the psychological techniques used by car salespeople, here is a good and brief introduction to purchasing a new car. Much of it stems from keeping your options open and never allowing yourself to feel pressured into buying a car. This is something I try and drive home to people in therapy or in any other interactions I have with them – keep the control in you life within yourself. Do not allow other people or circumstances to control your life. You have the power and choice to act for yourself. Yes, other people and circumstances influence all of us but only we have the ability to choose how we act.
In a sales situation, the buyer always has the power because the buyer can walk away at any time (barring a forced situation such as in slavery or when violence is threatened or in other such circumstances but I’m not writing about those at this time). Here is a good intro into buying a car. Warning: there is a brief instance of bad language in the video.
The American Academy of Neurology (AAN) has a site where you can donate to help fund brain research. All overhead for the donations are covered by AAN so all of your donated money will go directly to fund research into neurologic disorders. If you or a loved one suffer from a brain disorder or disease, this is a great way to potentially help others with neurologic disorders.
The minimum donation is $5.
Note: I am not affiliated with AAN or the donation site; I just think it is a great cause.
Here’s an old but good video of Carl Rogers giving an explanation of his Person Centered Therapeutic approach.
Here is the second part of the video where you can see Rogerian therapy in action:
Notice how Person Centered Therapy is non-directive. This means that the therapist does not provide answers for a client, the therapist helps clients work towards their own answers while being as supportive and reflective as possible.
There are more parts to the video, which can be found on YouTube.
Motivation is an area that many researchers study: psychologists, marketers, economists, sociologists, anthropologists, and just about any other field within the social sciences. Anything can motivate us – food, sex, sleep, rewards, pain – but what motivates us to perform better at work or in anything we do? This is the question addressed in the following video clip. This is one of the best introductions to motivation (especially as it applies to a business setting) that I’ve seen.
One of the prominent theories in social aging is role theory. Role theorists have shown that feeling in control of life and having social power and prestige is associated with better health (Krause et al., 1992). One of the major components of role theory is role loss. This occurs usually as people age; they start losing roles as active parents, employees, and spouses. This often leads to feelings of loss of control over life. In addition, older people generally have less contact with others which in turn causes their social networks to shrink. This leads to poorer health (Moen, Dempster-McClain, & Williams, 1992).
As people age they tend to lose social roles—whether as parents, employees, or spouses. This loss of roles can lead to social isolationism due to the decreased amount of social interaction. Research shows “that perceived social isolation [assuming that socially isolated people have few roles] is associated with a variety of altered physiological functions, such as blood pressure regulation…and immune reactions. A causal link in these relations was suggested…” (Berntson & Cacioppo, 2000, p. 9). Researchers also theorize the loss of roles as leading to loss of feelings of control and depressive symptoms, which are both components of overall well-being (Krause et al., 1992).
Van Willigen (2000) explains loss of control as composed of five different concepts: “powerlessness, isolation, self-estrangement, meaninglessness, and normlessness” (p. S309). She also explained that when people feel that they have power over their lives and are not socially isolated they generally have a greater psychosocial well-being. Consequently, when people do not feel in control of their lives and are isolated, they tend to have lower life satisfaction and well-being. These factors are in turn correlated with lower health and longevity (Hunter & Linn, 1981; Musick et al., 1999).
Rook and Sorkin (2003) posit a slightly different reason why role loss has negative consequences on older adults. They state:
For many older adults…dual ‘receiving and giving’ functions are readily available in their close relationships with other people…. For others, however, opportunities to express one or both functions may be missing. Widowhood, retirement, and other social role losses that affect the elderly may limit opportunities for maintaining and developing close relationships that involve reciprocal exchanges of support (p. 314).
They view roles as tied to reciprocal relationships and so without those roles they do not have others from which to benefit. While there is variation in explanations why role loss leads to poorer health, I did not address that with this post. I simply wanted to introduce one part of a social theory of aging.

I posted this on my neuroimaging blog and thought I should post it here too. This is a video I put together about the cingulum, a prominent white matter fiber track in the brain that is involved in emotion, attention, memory, among many other functions. All images except one from Gray’s Anatomy (the anatomy book, not the T.V. show) were created by me using some fairly advanced imaging techniques. If you are interested about some of the techniques, read my neuroimaging blog.
I’ve started an online structural neuroimaging guide for users of Mac OS X. The site can be found here. I am just beginning with it so there is not much information there yet but I hope to slowly expand it and make it a good resource for things related to neuroimaging, particularly structural MRI (including diffusion weighted images). My primary interests are with neuroimaging, neuroanatomy, and neuropsychology; I spend the bulk of my research time doing one of my favorite things – dealing with methods of neuroimaging analysis. While my role is not as technical as some of our collaborators, I enjoy the process of processing MRIs. In the process I have learned a great deal about imaging and wanted to put together a series of guides that will allow others, especially students and novices, to conduct their own analyses. There is a lot of very useful information out there but it is not consolidated into any one locale. One thing I plan on doing is consolidating much of the information into one place and making it easy to follow.
