SSRIs: Sharp Drop in Brain Activity + Worsening Depression & Suicidality

NOTE BY Ann Blake-Tracy (www.drugawareness.org):

Hopefully if you have followed my work or read my book, “Prozac: Panacea or Pandora? – Our Serotonin Nightmare,” you know that I have made the argument for a decade and a half that antidepressants are the most similar drugs we have ever seen to dissociative anesthetics like PCP or Ketamine. They just work in a little slower motion is all. This research would confirm that by showing adrop in brain activity within ONLY 48 hours of use! All one needs to do is go to the one color page inmy book with brain wave patterns of a 31 year old male on Prozac for six months. The brain waves show that the patient is in a total anesthetic sleep state and dreaming while talking with those doing the test on him!

Paragraph five reads:  “Prior research, Hunter said, has shown that between 8 and 14 percent of depressed patients develop thoughts of suicide while taking the most common forms ofdepression drugs, known as selective serotonin reuptake inhibitors (SSRI). Although reports have suggested that SSRIs are to blame, no firm link between these drugs and thoughts of suicide has been established.”

Paragraphs seven and eight read:  “The researchers treated 72 people suffering from majordepressive disorder (MDD) with one of two SSRIs, fluoxetine or venlafaxine, or with a placebo. All were evaluated by a clinician using the Hamilton Depression Rating Scale, a standard instrument that assesses the severity of a wide range of depression symptoms. Of the 37 participants on medication,five (13.5 percent) had worsening thoughts of suicide.”

“All of the participants were also examined using QEEG, which evaluates brain function based on thebrain‘s electrical activity. Among the 13.5 percent of participants who got worse, the researchersfound a sharp drop in brain activity within 48 hours of the start of medication. The dropoccurred in the midline and right-frontal sections of the brain, areas known to control emotions.”

SSRI Stories note:  In regard to placebo & suicidality, it should be remembered that the majority of placebo patients are ‘wash-out’ patients from other antidepressants and thus are actually inantidepressant withdrawal which can be extremely dangerous.

Simple test can detect signs of suicidal thoughts in people taking antidepressants

April 8, 2010 By Mark Wheeler

(PhysOrg.com) — UCLA researchers have developed a non-invasive biomarker that may serve as a type of early warning system for doctors and patients.

While antidepressant medications have proven to be beneficial in helping people overcome majordepression, it has long been known that a small subset of individuals taking these drugs can actually experience a worsening of mood, and even thoughts of suicide. No clinical test currently exists to make this determination, and only time  usually weeks  can tell before a psychiatrist knows whether a patient is getting better or worse.

Now, UCLA researchers have developed a non-invasive biomarker, or indicator, that may serve as a type of early warning system.

Reporting in the April edition of the peer-reviewed journal Acta Psychiatrica Scandinavica, Aimee Hunter, an assistant research psychologist in the UCLA Department of Psychiatry, and colleagues report that by using quantitative electroencephalographic (QEEG), a non-invasive measurement of electrical activity in the brain, they were able to observe a sharp reduction of activity in a specific brainregion in individuals who proved susceptible to thoughts of suicide  within 48 hours of the start of treatment.

Prior research, Hunter said, has shown that between 8 and 14 percent of depressed patients develop thoughts of suicide while taking the most common forms of depression drugs, known as selective serotonin reuptake inhibitors (SSRI). Although reports have suggested that SSRIs are to blame, no firm link between these drugs and thoughts of suicide has been established.

This study suggests, for the first time, a link between worsening suicidality and specific changes inbrain function while on these medications.

The researchers treated 72 people suffering from major depressive disorder (MDD) with one of twoSSRIs, fluoxetine or venlafaxine, or with a placebo. All were evaluated by a clinician using the Hamilton Depression Rating Scale, a standard instrument that assesses the severity of a wide range of depression symptoms. Of the 37 participants on medication, five (13.5 percent) had worseningthoughts of suicide.

All of the participants were also examined using QEEG, which evaluates brain function based on thebrain‘s electrical activity. Among the 13.5 percent of participants who got worse, the researchers found a sharp drop in brain activity within 48 hours of the start of medication. The drop occurred in the midline and right-frontal sections of the brain, areas known to control emotions.

Of note, eight of the 35 participants taking a placebo (22.9 percent) also had increased thoughts of suicide. However, the placebo participants did not show the precipitous drop in brain activity within the first 48 hours.

“This is the first study to show a change in brain function after the start of medication that appears to be linked to the subsequent development of worsening thoughts of suicide during antidepressant treatment,” Hunter said. “Importantly, changes in this biomarker did not predict worsening suicidal thoughts in the placebo-treated subjects, so the results suggest that the biomarker specifically detected medication-related worsening only.”

QEEG is a relatively inexpensive instrument that is non-invasive; measurements are obtained by placing electrodes on the scalp. As a result, Hunter said, further development of this biomarker could potentially lead to a tool that could be used by clinicians to predict, in the early stages of treatment, whether an individual suffering from depression will develop thoughts of suicide.

ANTIDEPRESSANT: Murder-Suicide: Mother Strangles her 2 Children: Kills Self

Paragraph 10 reads:  “Lo Wai-fan, a psychiatrist at East
Kowloon General Out-patient Clinic, said she met Lau in late October last
year
and prescribed her two-week’s worth of sleeping and
anti-depression drugs.
However, Lau turned up at the clinic on
November 6 – a week before her scheduled follow-up session – saying she was
suffering from insomnia and worrying about her son.”

Paragraphs three
through five read:  “But divorcee Lau Hoi-chu, 43, was released from Kwai
Chung Hospital on November 25 last year – two days before her mainland
friend Chen Shaozhen found Lau hanging in a bedroom
next to the body of

her son, Law Chung-yan, 16.

Her daughter, Law Yu-ching, 13, was
unconscious in another room in a flat in Lok On House, Tsz Lok Estate, Tsz Wan
Shan.

All three were certified dead by paramedics. The children were
apparently strangled.

Tormented mom told carers `she was ready
to kill’ –

Diana Lee

Tuesday,
November 24, 2009

A mentally-disturbed mother who was found hanged in

her flat near the strangled bodies of her two children told a psychiatrist she
“wanted to take her son’s life and then her own” three weeks before they died, a
coroner’s inquest was told yesterday.

Concerned she might injure herself
and others, she was sent to hospital for compulsory observation.

But
divorcee Lau Hoi-chu, 43, was released from Kwai Chung Hospital on November 25
last year – two days before her mainland friend Chen Shaozhen found Lau hanging
in a bedroom next to the body of her son, Law Chung-yan, 16.

Her

daughter, Law Yu-ching, 13, was unconscious in another room in a flat in Lok On
House, Tsz Lok Estate, Tsz Wan Shan.

All three were certified dead by
paramedics. The children were apparently strangled.

Testifying before a
jury of five, Chen said she took care of the children when Lau was in hospital.

She had a meal with the family shortly before their deaths and Lau
appeared to be at peace with her children.

Among the exhibits presented
in court was a calendar on which was scribbled “afraid to be admitted to
hospital again.”

In a written statement, Lau’s sister-in-law, Chen
Jianqing, said she moved into the flat on November 23 to help look after the
children together with Chen Shaozhen but on November 26 Lau told her not to
spend the night in the flat.

Lo Wai-fan, a psychiatrist at East Kowloon
General Out-patient Clinic, said she met Lau in late October last year and
prescribed her two-week’s worth of sleeping and anti-depression drugs. However,
Lau turned up at the clinic on November 6 – a week before her scheduled
follow-up session – saying she was suffering from insomnia and worrying about

her son.

Lau’s son, a Secondary Four student, had just been put on
probation for shoplifting.

“Lau was emotional and believed there was no
hope for the future. She said she wanted to end her son’s life before she ended
hers,” Lo said.

Fearing she might hurt herself and others, Lo had her
admitted to Kwai Chung Hospital under the Mental Health Ordinance for compulsory
psychiatric observation of at least seven days.

Kwong Lap-kuen, a
medical social worker, observed Lau and agreed with Lo’s diagnosis.

Chan
Wai-ping, an assistant social worker in the Social Welfare Department, said she
talked with Lau for more than an hour on November 19, during which she was calm
though she did express concern about finding a secondary school for her
daughter.

“She said it was just out of impulse when she said she wanted
to hurt herself and her son. She regretted what she had said, as she couldn’t
take care of her children while she was in hospital,” Chan said.

Lau
also wrote notes to remind herself of a “better tomorrow” and that “issues
concerning the growing up of the children do not equate to failure on my part.”

Lau’s ex-husband, Law Chi-pun, said he had not contacted her since 2006,
nor given her alimony.
