Study Notes on ECT, Lobotomy, and Phineas Gage's Case Study

In earlier times, many individuals with mental health issues were institutionalized in large state-run "lunatic asylums," which prioritized containment over rehabilitation.
The Deinstitutionalization movement, which gained momentum in the $1950$ s and $1960$ s, led to a decline in these facilities as treatments moved toward community-based care.
This shift was largely enabled by the $1954$ introduction of Chlorpromazine (Thorazine), the first effective antipsychotic medication.

Development of ECT
- ECT was developed in $1938$ by Italian psychiatrist Ugo Cerletti and his assistant Lucio Bini.
- Cerletti drew inspiration from observing hogs being subjected to electric shocks in a slaughterhouse in Rome to keep them docile before slaughter.
- The first human trial was conducted in April $1938$ on a man found wandering a train station; it was considered a success when the treatment reportedly cleared his confused mental state.
Mechanism of ECT
- High voltage electricity (ranging from $70$ to $400$ volts) is passed through the brain to induce a generalized seizure or convulsion.
- Historically, the lack of muscle relaxants resulted in severe physical side effects, including broken bones, tooth damage, and even death from cardiovascular stress.
- Although intended to calm patients, early iterations often left individuals in a vegetative state, leading to the "zombie" stereotype in media.
Perspectives on ECT
- Thomas Szasz and other leaders of the anti-psychiatry movement argued that ECT was an inhumane form of torture used for social control.
- Despite stigmas like long-term memory loss (retrograde amnesia), it remains a gold-standard treatment for severe, treatment-resistant depression.

Differences in Administration
- Bilateral ECT: Electrodes are placed on both temples. It is faster-acting but causes more significant memory impairment.
- Unilateral ECT: One electrode is placed on the temple of the non-dominant hemisphere, reducing cognitive side effects.
- Certain regulations today limit ECT in minors; for example, some states bar the procedure for individuals under $16$ .
- Modern ECT is performed under general anesthesia with muscle relaxants (like succinylcholine) to prevent physical injury, with sessions usually occurring $2$ to $3$ times a week for a total of $6$ to $12$ treatments.

Walter Freeman and the Lobotomy
- The procedure was adapted from Egas Moniz, who won the Nobel Prize in $1949$ for developing the leucotomy.
- Freeman popularized the transorbital lobotomy, using an ice-pick-like tool inserted through the eye socket to sever the connections in the prefrontal cortex.
- Freeman promoted it as a quick fix, even traveling in a "Lobotomobile" to perform the surgery on thousands of patients, sometimes without proper surgical masks or gloves.
Consequences of Lobotomies
- The procedure often resulted in a "blunting" of personality, where patients lost their initiative, emotions, and sense of self.
- Ethically, the procedure was catastrophic; Freeman performed it on children as young as $4$ years old.
- Rosemary Kennedy, sister of John F. Kennedy, underwent a lobotomy at age $23$ that left her with the mental capacity of a toddler, requiring lifelong institutional care.

Overview of Phineas Gage
- In $1848$ , Gage, a railroad foreman, was injured when a tamping iron— $3$ feet $7$ inches long and weighing $13.25$ pounds—was blown through his skull.
- The rod entered his left cheek and exited the top of his head, destroying much of his left frontal lobe.
- While he survived and remained conscious, his personality shifted from being hard-working and polite to becoming "fitful, irreverent, and profane."
Neuroscience and Neuroplasticity
- His case proved the localization of brain function, specifically that the frontal lobe is responsible for personality and social behavior.
- Gage also exemplified neuroplasticity—the brain's capacity to reorganize itself. After his injury, he moved to Chile and worked as a stagecoach driver, a job requiring significant coordination and social interaction, suggesting some functional recovery.

Understanding Brain Function and Treatment
- Modern science focuses on more precise interventions, such as Transcranial Magnetic Stimulation (TMS) or Deep Brain Stimulation (DBS), which are less invasive than ECT or lobotomy.
- Music therapy and art therapy are utilized to engage multiple brain regions, helping to stimulate memory and emotional regulation in patients with brain damage.
Long-Term Outcomes
- Gage lived for $12$ years after his accident, eventually dying from status epilepticus (prolonged seizures) in $1860$ .
- His legacy continues to inform how brain injuries are treated, emphasizing that while recovery is possible via adaptation, some structural changes result in permanent shifts in human identity.
