My Valentine’s memory would work this way even if I were dredging it up now for the first time ever. But the fact is that I’ve re-remembered that February morning countless times since then. I’ve told the story to my brothers. I’ve offered it as an Outrageous Mother Incident to friends of mine who enjoy that kind of thing. I’ve even, shameful to report, told people I hardly know at all. Each succeeding recollection and retelling reinforces the constellation of images and knowledge that constitute the memory. At the cellular level, according to neuroscientists, I’m burning the memory in a little deeper each time, strengthening the dendritic connections among its components, further encouraging the firing of that specific set of synapses. One of the great adaptive virtues of our brains, the feature that makes our gray matter so much smarter than any machine yet devised (my laptop’s cluttered hard drive or a World Wide Web that insists on recalling, in pellucid detail, a Beverly Hills 90210 fan site last updated on 11/20/98), is our ability to forget almost everything that has ever happened to us. I retain general, largely categorical memories of the past (a year spent in Spain; various visits to Indian restaurants on East Sixth Street) but relatively few specific episodic memories. Those memories that I do retain I tend to revisit and, thereby, strengthen. They become literally—morphologically, electrochemically—part of the architecture of my brain.
This model of memory, which I’ve presented here in a rather loose layperson’s summary, excites the amateur scientist in me. It feels true to the twinned fuzziness and richness of my own memories, and it inspires awe with its image of neural networks effortlessly self-coordinating, in a massively parallel way, to create my ghostly consciousness and my remarkably sturdy sense of self. It seems to me lovely and postmodern. The human brain is a web of a hundred billion neurons, maybe as many as two hundred billion, with trillions of axons and dendrites exchanging quadrillions of messages by way of at least fifty different chemical transmitters. The organ with which we observe and make sense of the universe is, by a comfortable margin, the most complex object we know of in that universe.
And yet it’s also a lump of meat. At some point, maybe later on that same Valentine’s Day, I forced myself to read the entire pathology report. It included a “Microscopic Description” of my father’s brain:
Sections of the frontal, parietal, occipital, and temporal cerebral cortices showed numerous senile plaques, prominently diffuse type, with minimal numbers of neurofibrillary tangles. Cortical Lewy bodies were easily detected in H&E stained material. The amygdala demonstrated plaques, occasional tangles and mild neuron loss.
In the notice that we had run in local newspapers nine months earlier, my mother insisted that we say my father had died “after long illness.” She liked the phrase’s formality and reticence, but it was hard not to hear her grievance in it as well, her emphasis on long. The pathologist’s identification of senile plaques in my father’s brain served to confirm, as only an autopsy could, the fact with which she’d struggled daily for many years: like millions of other Americans, my father had had Alzheimer’s disease.
This was his disease. It was also, you could argue, his story. But you have to let me tell it.
ALZHEIMER’S IS A DISEASE of classically “insidious onset.” Since even healthy people become more forgetful as they age, there’s no way to pinpoint the first memory to fall victim to it. The problem was especially vexed in the case of my father, who not only was depressive and reserved and slightly deaf but also was taking strong medicines for other ailments. For a long time it was possible to chalk up his non sequiturs to his hearing impairment, his forgetfulness to his depression, his hallucinations to his medicines; and chalk them up we did.
My memories of the years of my father’s initial decline are vividly about things other than him. Indeed, I’m somewhat appalled by how large I loom in my own memories, how peripheral my parents are. But I was living far from home in those years. My information came mainly from my mother’s complaints about my father, and these complaints I took with a grain of salt; she’d been complaining to me pretty much all my life.
My parents’ marriage was, it’s safe to say, less than happy. They stayed together for the sake of their children and for want of hope that divorce would make them any happier. As long as my father was working, they enjoyed autonomy in their respective fiefdoms of home and workplace, but after he retired, in 1981, at the age of sixty-six, they commenced a round-the-clock performance of No Exit in their comfortably furnished suburban house. I arrived for brief visits like a U.N. peacekeeping force to which each side passionately presented its case against the other.
Unlike my mother, who was hospitalized nearly thirty times in her life, my father had perfect health until he retired. His parents and uncles had lived into their eighties and nineties, and he, Earl Franzen, fully expected to be around at ninety “to see,” as he liked to say, “how things turn out.” (His anagramatic namesake Lear imagined his last years in similar terms: listening to “court news,” with Cordelia, to see “who loses and who wins, who’s in, who’s out.”) My father had no hobbies and few pleasures besides eating meals, seeing his children, and playing bridge, but he did take a narrative interest in life. He watched a staggering amount of TV news. His ambition for old age was to follow the unfolding histories of the nation and his children for as long as he could.
The passivity of this ambition, the sameness of his days, tended to make him invisible to me. From the early years of his mental decline I can dredge up exactly one direct memory: watching him, toward the end of the eighties, struggle and fail to calculate the tip on a restaurant bill.
Fortunately, my mother was a great writer of letters. My father’s passivity, which I regarded as regrettable but not really any of my business, was a source of bitter disappointment to her. As late as the fall of 1989—a season in which, according to her letters, my father was still playing golf and undertaking major home repairs—the terms of her complaints remained strictly personal:
It is extremely difficult living with a very unhappy person when you know you must be the major cause of the unhappiness. Decades ago when Dad told me he didn’t believe there is such a thing as love (that sex is a “trap”) and that he was not cut out to be a “happy” person I should have been smart enough to realize there was no hope for a relationship satisfactory to me. But I was busy & involved with my children and friends I loved and I guess, like Scarlett O’Hara, I told myself I would “worry about that tomorrow.”
This letter dates from a period during which the theater of my parents’ war had shifted to the issue of my father’s hearing impairment. My mother maintained that it was inconsiderate not to wear a hearing aid; my father complained that other people lacked the consideration to “speak up.” The battle culminated Pyrrhically in his purchase of a hearing aid that he then declined to wear. Here again, my mother constructed a moral story of his “stubbornness” and “vanity” and “defeatism”; but it’s hard not to suspect, in hindsight, that his faulty ears were already serving to camouflage more serious trouble.
A letter from January 1990 contains my mother’s first written reference to this trouble:
Last week one day he had to skip his breakfast-time medication in order to take some motor skills tests at Wash U. where he is in the Memory & Ageing study. That night I awakened to the sound of his electric razor, looked at the clock & he was in the bathroom shaving at 2:30 AM.
Within a few months my father was making so many mistakes that my mother was forced to entertain other explanations:
Either he’s stressed or not concentrating or having some mental deterioration but there have been quite a few incidents recently that really worry me. He keeps leaving the car door open or the lights on & twice in one week we had to call triple A & have them come out & charge the battery (now I’ve posted signs in the garage & that seems to have helped) … I really don’t like the idea of leaving him in the house alone for more
