In 1935, neurophysiologist John Farquhar Fulton
0
6878
5297
00:12
presented some shocking new research.
1
12175
2502
00:15
After removing the frontal lobes of two chimps,
2
15094
3504
00:18
he found they no longer experienced frustration or anxiety.
3
18723
4963
00:24
As his research associate noted, it was as if they’d joined a “happiness cult.”
4
24062
5630
00:30
Admittedly, the surgery had cost Fulton’s chimps some cognitive functions.
5
30193
5338
00:35
But to Portuguese neurologist Egas Moniz,
6
35740
3253
00:39
this was a small sacrifice for what seemed to be eternal happiness.
7
39077
5338
00:44
Moniz believed that replicating this procedure in humans
8
44791
3878
00:48
could cure mental illness.
9
48669
1919
00:50
And it was this therapeutic intention
10
50671
2711
00:53
that led to one of the most controversial and destructive
11
53382
3462
00:56
medical treatments of the 20th century:
12
56844
2795
00:59
the lobotomy.
13
59639
1126
01:01
Today, we know mental illness comes in many forms and emerges for many reasons.
14
61432
6256
01:07
But in the early 20th century,
15
67855
2127
01:09
these complex conditions weren't clearly delineated,
16
69982
3879
01:14
and researchers had various theories about their origins.
17
74028
4129
01:18
Moniz believed the symptoms of what we now call depression, OCD, and bipolar disorder
18
78366
6673
01:25
stemmed from negative ideas getting fixed in the neural fibers
19
85206
5172
01:30
which connect different parts of the brain.
20
90378
2753
01:33
Specifically the thalamus and frontal lobes,
21
93297
3504
01:36
which regulate emotion and sensation.
22
96884
2795
01:40
He proposed that severing these fibers could eliminate the associated conditions,
23
100179
5714
01:45
which led him to invent the prefrontal lobotomy.
24
105977
3628
01:50
In this procedure, a surgeon would drill into the skull and cut the white matter
25
110022
5840
01:55
connecting the prefrontal cortex to the rest of the brain.
26
115862
3878
02:00
Initially, his peers were skeptical.
27
120116
2836
02:03
Moniz’s fundamental theory was already controversial.
28
123161
3837
02:07
And psychiatrists advocating for treatments like psychoanalysis
29
127290
4296
02:11
criticized this invasive surgical solution.
30
131586
3044
02:14
But Moniz was undeterred.
31
134922
2002
02:16
He lobotomized 38 individuals with conditions including anxiety,
32
136966
5172
02:22
schizophrenia, and depression.
33
142138
2377
02:24
And his hastily written results reported that two-thirds of these patients
34
144849
4755
02:29
had become tranquil, amicable, and free from distressing hallucinations.
35
149604
4838
02:34
At the time, psychiatrists saw calm behavior as a sign of recovery,
36
154775
5506
02:40
so when Moniz brashly declared the treatment a success,
37
160364
3838
02:44
his peers agreed.
38
164202
1543
02:46
Newspapers celebrated the surgery;
39
166537
2211
02:48
Moniz was awarded the Nobel Prize;
40
168789
2461
02:51
and his procedure became especially popular in the US
41
171250
3796
02:55
thanks to neurologist Walter Freeman and neurosurgeon James Watts.
42
175129
4838
03:00
As a country that had institutionalized nearly half a million people
43
180343
4337
03:04
for mental health reasons,
44
184680
1585
03:06
many hoped the new treatment would allow this population
45
186265
3921
03:10
to live relatively normal lives.
46
190186
2210
03:12
But from the beginning there were problems.
47
192730
2753
03:15
First, the notion of a “normal life”
48
195983
2795
03:18
was determined by this period’s restrictive social mores,
49
198778
3837
03:22
which had led huge numbers of people to be institutionalized
50
202740
3962
03:26
simply because they didn’t conform.
51
206702
2294
03:29
So, while many people in these facilities did need medical help,
52
209247
4129
03:33
some lobotomy recipients had no mental illness whatsoever.
53
213376
4379
03:38
Second, the details and timeline of the surgeries’ results
54
218130
4380
03:42
were unpredictable and inconsistent.
55
222510
2794
03:45
In 1941, when future US President John F. Kennedy’s sister Rosemary
56
225721
5381
03:51
underwent a prefrontal lobotomy,
57
231185
2586
03:53
it permanently impaired her ability to speak and walk.
58
233771
4046
03:58
And even when the surgery did help patients manage
59
238067
2961
04:01
overwhelming emotions and hallucinations,
60
241028
2544
04:03
they often experienced significant side effects.
61
243572
3087
04:06
These included apathy, abrupt personality changes, and cognitive impairment.
62
246826
5797
04:13
Tragically, the stigma around mental illness kept people from discussing
63
253207
4755
04:17
their negative experiences,
64
257962
1877
04:19
so the procedure kept happening.
65
259839
2085
04:22
But prefrontal lobotomies required a team of surgeons and specialized equipment,
66
262174
5548
04:27
making them out of reach for most patients.
67
267930
2628
04:30
At least until 1945,
68
270683
2794
04:33
when Freeman began developing a simpler and cheaper alternative.
69
273477
4380
04:38
In his new transorbital lobotomy,
70
278107
2628
04:40
the patient was first rendered unconscious via electroshock therapy.
71
280860
4629
04:45
Then, an ice pick-like instrument
72
285573
2627
04:48
was pushed through the thin bone of their eye socket
73
288284
3295
04:51
and manipulated to sever the fibers
74
291662
2795
04:54
between the thalamus and frontal lobes.
75
294457
2377
04:57
Transorbital lobotomy was intended to be performed by physicians
76
297168
4379
05:01
without surgical training in under ten minutes.
77
301547
3629
05:05
And Freeman proved his procedure’s efficiency during a hospital visit,
78
305384
4338
05:09
where he performed the surgery 228 times in just 12 days.
79
309847
6006
05:16
Transorbital lobotomy was immediately controversial.
80
316437
3587
05:20
Even Freeman’s long-time collaborator James Watts
81
320441
3462
05:23
was against making such a consequential surgery
82
323986
3003
05:26
quick, dirty, and accessible to amateurs.
83
326989
2878
05:30
But the procedure remained popular throughout the Western world
84
330034
3462
05:33
until the 1950s,
85
333496
1585
05:35
when tranquilizers began offering a less permanent
86
335247
3587
05:38
and more predictable alternative.
87
338834
2002
05:41
By the mid-60s, lobotomies were most often found in science fiction and horror films,
88
341420
5839
05:47
where they became a potent metaphor
89
347385
2085
05:49
for brutally controlling those who don't fit the norm.
90
349470
3712
05:53
Today, lobotomy serves as a chilling reminder that scientific progress
91
353474
5213
05:58
requires transparency and clear ethical standards.
92
358687
3629
06:02
Because without honest reflection,
93
362400
2085
06:04
even efforts to alleviate human suffering can cause serious harm.
