Hidden Valley Road: Inside the Mind of an American Family

The summary

Between the 1960s and the 1980s, six of the twelve Galvin children — all of them boys — developed schizophrenia. That single, staggering fact turned an ordinary Colorado family into one of the most important case studies in the history of mental illness. Robert Kolker tells two stories at once: how the Galvins’ shared DNA helped drag schizophrenia research away from decades of mother-blaming folklore and toward genetics and brain science, and how the healthy children paid for that contribution with childhoods and adult lives shaped entirely by the illness around them.

Twelve children, and then the unraveling

Mimi and Don Galvin married young, had twelve children in quick succession, and settled on Hidden Valley Road as Don built a career in the new Air Force. The first signs looked like ordinary adolescent trouble. The two oldest boys, Donald and Jim, brawled. Jim was expelled for sneaking into a jet. Donald smashed dishes and once jumped into a bonfire. It was easy to file all of it under teenage chaos — until Donald, after a relationship collapsed, admitted to a psychiatrist that he’d attempted suicide and killed a cat he couldn’t explain killing. The diagnosis was a “possible schizophrenic reaction.” At home he shouted that the CIA was shooting at him. Then Jim began hearing voices and compulsively switching stove burners on and off. When his wife reported it, his parents brushed her off and never mentioned Donald. The pattern would repeat until six brothers were ill.

The cost of keeping it quiet

In the 1960s, the reigning theory blamed the “schizophrenogenic mother” — a woman supposedly too cold or too smothering, either way at fault. That, plus the era’s brutal treatments of shock therapy, restraints, and heavy tranquilizers, made Mimi and Don refuse to commit their sons. So the sick brothers stayed home, and the household absorbed the consequences. Donald moved the furniture outside and lay naked reciting scripture. The two youngest sisters, Margaret and Mary, fled to their brother Jim’s house for relief, only for Jim to molest them when drunk; frightened and unsure, they kept it secret for years. In 1973 Brian, the fourth son, shot his girlfriend Noni and then himself. Two years later Don suffered a disabling stroke, and soon Peter, the youngest boy, began speaking gibberish and turning violent. Mary got out, escaping to a Connecticut boarding school and renaming herself Lindsay to start clean — though the family’s pull never quite let go.

From blaming mothers to reading brains

By the late 1970s, science was finally turning from parents toward biology. The neuropsychiatrist Richard Wyatt found that people with schizophrenia tended to have enlarged fluid-filled ventricles near the amygdala and hippocampus, and that larger ventricles tracked with drugs working less well. In 1984 the psychiatrist Lynn DeLisi began gathering genetic data from families with multiple cases, and the Galvins were close to ideal; Mimi provided blood from across the family. The pivotal insight came from Robert Freedman’s study of sensory gating — the brain’s ability to tune out a repeated stimulus. Most people react less to a sound the second time; people with schizophrenia react as though every time is the first. Freedman argued this same hypersensitivity explained the mathematician John Nash, who detected patterns no one else could and also feared enemies who weren’t there. Testing the Galvins, Freedman traced the problem to the brain’s α7 nicotinic receptor, of which people with schizophrenia have roughly half the normal number. Nicotine eased symptoms briefly; a drug called DMXBA worked better but went undeveloped once its patent neared expiry. Most promising, Freedman found that choline, a common nutrient, could switch on the gene that builds α7 receptors — leading to efforts to add it to prenatal vitamins, with encouraging early results.

What the family’s DNA revealed

DeLisi kept working the Galvin DNA for decades, even after a corporate buyout killed her funding and she had to rebuild the project with a new partner. Together they pinpointed a mutation in SHANK2, a gene governing communication between synapses, and their 2016 work tied the SHANK genes to a whole spectrum of conditions including autism and bipolar disorder. That reframed schizophrenia itself: less a single disease than a cluster of neurodevelopmental disorders. As the psychiatrist John McGrath put it, psychosis may be more like a fever — a symptom thrown off by many underlying illnesses — than a disease in its own right.

The bottom line

The Galvins gave science a genetic key to schizophrenia, but the payoff has come slowly: Jim and Joe died in their fifties from medication-related heart trouble, drug development stays sluggish, and prevention research remains starved of money. When DeLisi returned in 2016, it was Lindsay — the sister who ran the farthest — who had become the family’s caretaker, proof that we are never only our genes but also the people we’re raised among.
