Common Medication and Vision Side Effects

 Apparently, there are a bunch of medicines that don't play well with vision problems.

 Some of the anti-psychotic  medicines affect accommodation, produce blurred or double vision or impact the visual field include:  Zoloft, Risperidal, Wellbutrin, Paxil, Citalopram.   Even though this article doesn't point out Xanax or other benzodiazepans as being problematic, they have come up on other lists.  Since a lot of folks with strabismus often suffer from anxiety, depression, or social anxiety and are prescribed these  medications, they may be worsening some of the problems they are working so hard in vision therapy to correct.

Other medications impacting vision include antihistamines including Zyrtec, and a number of hypertensives.

Growling tummy: Sulphite preservatives

I think I am also sensitive to sulphites.... While I have always known that I am allergic to sulfa drugs, I never connected the fact that I don't tolerate wine very well to sulfites.... who'd a thunk that the two were connected.  

Here's a nice fact sheet on sulfites.

Mean response times, variability, and sk... [Acta Psychol (Amst). 2000] - PubMed - NCBI

Response time (RT) distributions from three fixed foreperiod conditions (2, 4, and 8 s) in a warned four-choice RT task were obtained for a group of boys with attention-deficit/hyperactivity disorder, combined type (ADHD; n = 17) and for two groups of normal control boys (age-matched, n = 18, and younger-aged, n = 10). Quantitative measures of distributional shape were derived by fitting the ex-Gaussian distributional model to the individual RT data. Statistical results indicate that the ADHD distributions differ from the age-matched control distributions with respect to the size of the tail (larger for the ADHD boys), but differ from the younger control distributions with respect to the location of the leading edge (slower for the younger control boys). Receiver operating characteristic (ROC) results reveal that the ex-Gaussian exponential component is highly diagnostic of the ADHD boys.

Adhd and alcohol

  1. Frequent heavy drinking in early adulthood, particularly prior to age 21, is associated with multiple health and legal consequences including continued problems with drinking later into adulthood. Children with attention-deficit/hyperactivity disorder (ADHD) are at risk of alcohol use disorder in adulthood, but little is known about their frequency of underage drinking as young adults or about mediational pathways that might contribute to this risky outcome. The current study used data from the Pittsburgh ADHD Longitudinal Study to test social impairment and delinquency pathways from childhood ADHD to heavy drinking in early adulthood for individuals with (n = 148) and without (n = 117) childhood ADHD. Although ADHD did not predict heavy drinking, indirect mediating effects in opposing directions were found. A delinquency pathway from childhood ADHD to increased heavy drinking included adolescent and subsequently adult delinquent behavior. A social impairment pathway from childhood ADHD todecreased heavy drinking included adolescent, but not adult, social impairment. These findings help explain the heterogeneity of results for alcohol use among individuals with ADHD and suggest that common ADHD-related impairments may operate differently from each other and distinctly across developmental periods.

Getting my eyes lined up with my new glasses

Got my new glasses.  I get a lot more peripheral vision and a bit more of a sense of space but my eyes are hurting.  So I had the optician double check the lenses.  In fact had two opticians double check the lenses and they are OK.  So went and had another visit to the optometrist.

He thinks we have a bit of a dilemma. We can decrease the amount of prism and my eyes won't be aligned as much but I will be more comfortable.  Or we can leave them as is.  He is trying to pinpoint the exact nature of the problem...whether it has something to do with binocularity or something else.  I looks at a test for far fixation with a red and green cross.   I could make the cross but it was jiggling.
So he patched me for twenty minutes with each eye.  Each eye was relieved a bit and the pain diminished but not completely.  We thought it might be better to do a day test patching an eye starting in the morning as my eyes get quite tired with these new glasses and see what happens.

We might cut the prism and start with a lower power prism and I might go back to home exercises and work on aligning a bar on my TV set.

Profiles of the gifted and talented


Profiles of the Gifted and Talented
The following presentation of six different profiles of gifted and talented students can provide information for educators and parents about the behavior, feelings, and needs of gifted and talented children and youth. It is important to remember that this is a theoretical concept that can provide insights for facilitating the growth of the gifted and talented, not a diagnostic classification model.

The six different types are:  successful, challenging, underground, dropout, double labeled, autonomous learner....

Circling back

Have had two interesting observations.

Went to an optometrist who specializes in strabismus.  Unlike everyone else, he didn't  do fifty million tests.  Did the visagraph and also checked my binocular vision.   I have 30 degrees of stereopsis...fantastic binocular vision... But still not much depth perception,  so he did two more tests:  test of near point fixation and far point fixation which found that my the lines are shifted to the left; they are aligned horizontally, no problem.He wrote a new prescription that added a basein prism to the left eye and had an interesting comment that my problems may be processing information.

Went to neurofeedback. We have been doing alpha synchrony training with OpenFocus.  My alpha/theta ratio is 1.5 at the beginning of the session, towards the middle, it moves towards 1. 0, and occasionally alpha dips below 1.  So I have good concentration.  These waves are not characteristic of someone who has Adhd.... So my therapist feeling is that maybe I have a processing problem not a concentration or attention problem.

So where does this lead me?   Back to the learning disability world?  Hmmm.
