Debunking four myths about decision-making capacity to keep Britney Spears and others safe

by

Brit­ney Spears’ impas­sioned remarks in court have raised many ques­tions about con­ser­va­tor­ships, includ­ing when they’re nec­es­sary and whether they effec­tive­ly pro­tect someone’s best interests.

When one los­es the capac­i­ty to make deci­sions for one­self the court appoints a guardian, or con­ser­va­tor, to make those deci­sions. Appoint­ing some­one to make deci­sions about per­son­al and finan­cial mat­ters on another’s behalf has been part of civ­il soci­ety since the ancient Greeks. Today, all juris­dic­tions in the U.S. have con­ser­va­tor­ship laws to pro­tect peo­ple who lack the abil­i­ty to make their own deci­sions.

Initial study finds promise and limitations in using virtual reality (VR) to treat ADHD

Giv­en the lim­i­ta­tions of exist­ing evi­dence-based ADHD treat­ments, i.e., stim­u­lant med­ica­tion and behav­ior ther­a­py — research on nov­el inter­ven­tion approach­es con­tin­ues to be important.

Cog­ni­tive train­ing is one such approach that has been sug­gest­ed as a poten­tial adjunct or even replace­ment for med­ica­tion treat­ment. While cog­ni­tive train­ing takes dif­fer­ent forms, e.g., com­put­er­ized atten­tion train­ing, work­ing mem­o­ry train­ing, the basic idea is that by repeat­ed­ly prac­tic­ing cog­ni­tive tasks relat­ed to atten­tion, one’s abil­i­ty to focus and attend will improve. In oth­er words, [Read more…] about Ini­tial study finds promise and lim­i­ta­tions in using vir­tu­al real­i­ty (VR) to treat ADHD

Jan Samzelius, CEO of Brainnovations Winner NeuraMetrix, encourages pioneers to focus on “simple, elegant solutions to big problems”

What sur­prised you the most from the Judges’ ques­tions and feed­back dur­ing the Brain­no­va­tions Pitch Con­test last month?

Even with only a brief pre­sen­ta­tion the judges imme­di­ate­ly got the poten­tial impact of our tech­nol­o­gy to mea­sure and mon­i­tor brain health and began to think about oth­er appli­ca­tions for us – sev­er­al we had not thought about. That was fun.

In a nut­shell, what is the core idea behind Neu­raMetrix?

Typ­ing Cadence is among the strongest habit we have. If the brain is attacked by a dis­ease, the habit will begin to break – very slow­ly and in very small incre­ments. Our way of mea­sur­ing is so sen­si­tive that we can pick up changes at the lev­el of 1/100th of sec­ond – many orders of mag­ni­tude bet­ter than today’s tools.

When and how did the idea come to you?

Com­ing from data secu­ri­ty, our first idea was to use typ­ing cadence for authen­ti­ca­tion, and then were alert­ed to the brain health appli­ca­tion by an out­sider.

Non-invasive brain stimulation in children creates opportunities and risks

TMSvtDCSBrain Stim­u­la­tion in Chil­dren Spurs Hope—and Con­cern (Sci­en­tif­ic American):

“The idea of using mag­nets or elec­tric cur­rents to treat psy­chi­atric or learn­ing dis­or­ders — or just to enhance cog­ni­tion — has gen­er­at­ed a flur­ry of excite­ment over the past ten years. The tech­nique is thought to work by acti­vat­ing neur­al cir­cuits or by mak­ing it eas­i­er for neu­rons to fire. The research is still in its infan­cy, but at least 10,000 adults have under­gone [Read more…] about Non-inva­sive brain stim­u­la­tion in chil­dren cre­ates oppor­tu­ni­ties and risks

Dif­fer­ent men­tal dis­or­ders cause same brain-mat­ter loss, study finds (press release):

“A meta-analy­sis of 193 brain-imag­ing stud­ies shows sim­i­lar gray-mat­ter loss in the brains of peo­ple with diag­noses as dif­fer­ent as schiz­o­phre­nia, depres­sion and addiction…The find­ings call into ques­tion a long­stand­ing ten­den­cy to dis­tin­guish psy­chi­atric dis­or­ders chiefly by their symp­toms rather than their under­ly­ing brain pathol­o­gy.
